Well, was out tonight. Pulled over & the engine cut. I had the aircon running, and it does tend to lower the revs.
Anyway, tried to restart it, but it was having none of it. Decided to let it cool for a while, but it still didn\'t want to go. Engine was trying to fire but not quite getting there. Left it longer, tried it with fuel relay out & it was doing the same.
My mate came out & we connected some heavy duty jump leads up to his L200. Was still doing the same, though. Tried it with fuel relay out & it\'s still trying to fire.
In the end, we decided to hook it up to his towbar & bump started. It started running from that straight away, but as soon as I tried to let it idle, it cut back out. So we bumped it again & I drove it steadily back home.
Now, on the way back it was refusing to go past 2500/3000 rpm. It would really pull back hard & then backfire loudly. Seemed to be whenever the turbos are trying to spin up, it doesn\'t want to pull!
Got it home & it has the same starting problems!
So, anyone have any ideas on this. Sorry for posting such a long story for something that I could probably have explained in a couple of lines, but I thought it might be better to give an exact description of what was happening.
Thanks :Thumbs-up

What do you mean by "fuel relay" ?
Ooops, sorry. I mean the fuel pump relay in the black box near the slam panel.
Was it running roughly too?
What exactly were you doing prior to pulling over?
ok, if you think it was flooded, then removing the fuel pump relay does NOT stop the pump from pumping. The relay only adds/removes a resistor into the fuel pump circuit, I think its to change the speed or the pressure.
You need to remove the egi fuse if you want the fuel to stop pumping.
Sounds to me like you dont have a flooding problem, though. I think you have a massive air leak somewhere. It also sound like the ecu needs to be reset - remove a battery terminal, press the brake pedal, and reconnect.
What ECu do you have and what mods do you have?

I had a similar prob with the backfiring, check your battery terminals & the wires from them, I checked all the connections coming fron the ternails tightened one every so slightly & the prob was gone
I still have the standard ECU at the moment. Only mods are exhaust, filters & dump valve.
Tried to start it this morning and it was having none of it. Was smelling strongly of fuel, too.
It wasn\'t really running "rough" after we bump-started it, just wouldn\'t really go much above 3000 rpm, where it just kept heavily pulling back & massively backfiring. But if I\'d have let the revs drop right down it would have cut out, which it did once I\'d reached home & got on the driveway. But it seemed to be driving normally in those low revs, other than that.
make sure the vacuum signal hose has not come off the map/boost sensor
As per blitzboy, but also check the vacume line to the fuel pressure reg, if it isnt reading boost or vacume, it wont increase/decrease fuel pressure. So at idle you will have too much fuel pressure and when it starts to boost, you wont have enough.
hi
can someone tell me where the map/boost sensor is plz
Quotemake sure the vacuum signal hose has not come off the map/boost sensor
I would say this too.
The map sensor is here:
I hadn\'t thought of checking the map sensor. Unfortunately the vac pipe is still securely connected.
Where is the fuel pressure regulator, so I can check that vac line, as that sounds like a likely suspect.
its on the end of the secondary rail under the inlet manifold i\'m afraid
oh! :( That doesn\'t sound too easy! That\'s gonna mean removing a fair bit, I guess?
Hate the way that I sound like a total noob. I\'m usually good with a lot of engines, but I\'m still getting to grips with this!
EDIT: Aha! just found a disconnected pipe. Kind of down the back of the engine near the bulkhead/firewall there\'s a pipe off. Gonna try & get it back on without removing too much. Typical that it\'s in such an awkward spot!
EDIT 2: Still not starting. It\'s trying to fire but not managing it. Although that\'s what it was doing anyway. Took top 2 plugs out & they\'re pretty soaked, though.
If it\'s flooded,even after the cause has been fixed, you\'ll need to dry off the plugs, warm them, run it w/out the egi fuse or plugs to clear the excess fuel - don\'t want to be smoking at this point - then put the plugs back in, egi fuse back in and you should be ok (if you have found the cause of the flooding that is)
it may be the pipe that you have seen off as you can just about see the FPR down between the bulk head and the UIM.
Cool.
Pretty sure it\'s flooded, through trying to start it, so after work I\'m gonna get the plugs out, etc. Hopefully I\'ll be posting to say it\'s up & running a little later.:driving
Did all the deflooding. Plugs out, burnt off petrol, cleaned them up. Took egi out, turned it over a few times. Plugs in, egi in, and after the usual shaky bits of firing, it fired up. Revs were going past 3000rpm fine, too. Except I had to sit with it running on the drive as my bonnet was still open & nobody was home. I didn\'t wanna completely take my foot off the accelerator cuz it would probably cut out!
So, let it get to normal operating temperature. But after a while I took my foot right off & the revs dropped a bit too low & it cut out. Tried to re-start it, but it was having none of it. Just "slightly" attempting to fire for the 1st second or so, then nothing.
Now, I\'m back to square one! :( So, I took all the plugs out again, cleaned them up again, took egi out, turned it over, put everything back in, but it still doesn\'t want to start.
Is it best to leave it and do it when it\'s cold?
Also, the plugs were pretty black after I took them out the second time. Although I\'ve suspected it\'s running too rich for a while. But is there a way to make it run more lean or is it a case of waiting till I get a PFC?
Gonna try the deflooding again tomorrow night after the football. Charging the battery at the mo as I\'ve given it quite a caning and could probably do with making sure it will give a decent spark!
If that doesn\'t work, then I\'m back to the beginning cuz I don\'t know what would be causing it, then!
Been attempting to deflood it this evening. I\'ve had the plugs out, egi out, turned it over a few times, egi & plugs back in, etc, 4 times now, and every time the plugs are just getting soaked in petrol in a matter of seconds.
No idea what to do now, though. It just floods all the time. Strange that it got running the other day, though. But this time it\'s having none of it. :confused:
It\'s just beginning to annoy me now :Grrr . I\'m recharging the battery again now, because I\'ve given it such a drain in trying to get it going so much!
So, I really have no idea what to do next. (get a Supra or Skyline sounds like the easiest answer at the mo!!!!! :eek: ).
Tow start, works nearly every time. Even with the most temperamental non starter ;)
Once running, give it a really good long drive to give it a good clear through :)
*edit* just read the rest of your post, not so straightforward then by the sound of things :( but at least it\'ll run again.
Once started, rev the nuts off it, don\'t even think about letting it try to idle for a while on its own.
been reading about your problem i had the same thing happen to me all i did was fit new plugs and it runs fine now hope this my be off some help to you TJ
Yeah. Thinking of getting my mate over some time tomorrow to tow start it.
tj5ww, I recently put in new plugs. And a new battery, too.
Ok, its obviuos that something is wrong, not just a flooding problem.
So, I would next get the codes form the ecu. Seems to me something is telling it to pump loads of fuel in.

O.k. How do I get the ECU codes?
Gonna try a tow start later on & see what happens. Had got it running the other day after deflooding it & it wasn\'t playing up at 3000rpm like it had been the other night. So will cross my fingers. :)
EDIT: I\'ve got the plugs out again. It tends to be the top 2 plugs that seem to be getting really wet with petrol, the bottom 2 stay fairly dry. Is that normal? Well, I mean is that normal in a flooding kind of way?
EDIT 2: Did all the usual deflooding stuff. No suprise that it was having none of it & the top 2 plugs are soaked again! I\'m getting pretty fed up with it now, though. Lost count of how many times I\'ve had the plugs out. 12, maybe 13 times now?
The top 2 plugs are not AS exposed to the combustion chamber as the bottom 2 are, so this is normal.
I dont have a link to the codes, do a search on here or on google.
Ah, I see.
Found a thread that explains how to get the codes & what they mean. Will check that out & see if it gives me any ideas.
All right then ! Lets us know what you find.
Just a little update.
Not really tried to sort anything just yet, as been really busy at work. Took it for a run the other day. Also just gave it a run this evening.
It struggles a little on cold start, seems the firing has to "build up", but it runs o.k once it\'s going (apart from boost probs which will be getting sorted soon).
But tonight I decided to try something which I haven\'t tried since it gave up on me a couple of weeks ago..... Warm start. Left it for about half an hour, then tried to start it. And, as I suspected, it won\'t start. This wouldn\'t be too much of a problem as I\'m taking it over to Haywards next week to get everything sorted. The problem it does pose, though, is I\'m gonna need to stop for some fuel. And if I do that, the car isn\'t gonna start!!!!! :2eek :2Confused So any ideas? Or should I still find out what codes I get first?
