i cleaned the plugs and washed the car last night and drove it about 5 miles, everything was fine. so i parked it. when i went to drive it today it wouldnt start...just winds and winds and wont kick over. it tried to kick over once but that was the only time. well left it alone for a while then came back to it. same thing was happening so i cleaned the plugs again (they were black but didnt appear too bad) didnt help. so i started spraying starting fluid into the intake manifold it would kick over and run for about 3 seconds then die after i did this then it would just crank and crank so i repeated this about 4 or 5 times with the same outcome. i had a little ATF and put it in too. well worse came to worse so we tied it up behind my dads truck and pulled it around the block in 2nd gear it would run since it was being pulled but would die if i pushed in the clutch or pressed the gas any. i also made sure the all the ECU plugs were tight...has anyone had something similar to this happen to them?...

Clutch switch...

z4csl428

i read something about that after i searched but didnt think it could've been my problem how can i check/fix this? would it still be the clutch switch since the car didnt start while it was being pulled off?...

z4csl428

i just read that a faulty clutch switch will also cause the cruise control not to disengage whenever the clutch is depressed. this has happened to me anytime i try to depress the clutch when cruise control is on...

spekdah

can you hear any additional noises ( apart from the obviouse ones) when trying to start it?

z4csl428

not anything really noticeable...

If it was a clutch switch, I don't think it would even crank.

z4csl428

same thing i was thinking but it cant hurt and i have another symptom of a bad clutch switch(cruise control not disengaging).....

LMFAO...

Clint, you should know by now what I'm going to say. Check fuel, check spark, check compression. We already know you (better) have good compression, so check spark and fuel delivery. Pull your UIM and unbolt/lay back the lower fuel rail and crank the engine to check for fuel delivery accurately.


You could just have some fouled plugs, but it sounds electrical in nature. Perhaps your fuel pump took a ****...

That's basically it what rotary resurrection said. It sounds really basic but with all those three things in mind you can pretty much pinpoint anything. The problem is breaking it down after you find which one of those it is your having problems with.

Don't guess man do the first two easiest things first, check your spark and get that out of the way, test your compression and get that out of the way, if you have both of those than you know it is a fuel problem.

All your clutch switch is going to do is either prevent your car from cranking over, or producing a spark easy as that.

a compression test wouldnt hurt but i dont think its necessary at the moment. im gonna replace the clutch switch since i know its bad anyway. then move on to fuel pump since i recently installed one...

yes f/p to ground. But it isn't going to tell you if the fuel pressure is good, or if you have a bad injector. You could still have a weak f/p that will still shoot fuel out.

yup that is right. if it doesn't whirr, then it's done

That really sounds like a fuel delivery problem to me. BUt I am no rotary expert.

my reasoning is this: (and please correct em if i am wrong) The car will only kick over when you directly "feed" it combustables. But As soon as it uses that up, it dies. Sounds like the engine is not getting the normal supply of fuel. I dont think it would be a clutch switch, since most clutch switch applications will prevent the starter motor from even cranking the engine over. (this is based purely on my experience in car audio and electronics) I dont think it would be a compression issue since it runs normal when force fed. I could be very wrong here, but I am just trying to logically eliminate problems.

Please inform me if I am incorrect in any way, as i am very eager to learn everything I can here.

You guys are right, I doubt it's the clutch switch -- that's what I get for reading and posting in a hurry...

well i hotwired the fuel pump from the diagnosis box (F/P to GND) and when it was in the on position the fuel pump wouldn't make a sound. also the wire that i used to hotwire it started smoking and melted?...so im gonna go out and pull the supra pump i recently installed and see if i can see anything wrong if not then ill install the stock pump and see how that goes...

z4csl428

well i pulled the pump and everything appeared normal, when i took the two fuel lines off (two facing the front off the car) it spewed gas for a while out of the left one (from the back of the car) and had a lot of vacuum on the right one. so i guess that means i have fuel pressure if after all the things i did to try to start it and it still has this much pressure in the lines. so im gonna pull the injectors tomorrow and see whats going on there. im almost 100% positive that its somewhere in the fuel bc it sparks fine and the compression is good. are there any fuses that when blown would cause the engine not to get any fuel?

CantGoStraight

If it ran when spraying eyther into th intake and then died (fuel ran out) then I would imagine it's not getting any fuel. Said plugs were carboned (not wet) so it's not flooded. Wouldn't run when pulled (should have flooded the hell out of it if it was missing spark) and getting fuel. Lets see just installed fuel pump....might be a great place to start looking.

clint, you dont have to put the picture in your signature in EVERY post you make, you know. Once per thread is sufficient. There are like 10 red rx-7s in this thread.

As for your fuel pump, with the supply hose off, jumper it and see if it spits fuel out. IF it does, it's a pretty safe bet that it's doing what its supposed to. Next move on to the engine, pull your primary rail back and test for injection, which I already said above.

z4csl428

<<< happiest man in the world...i pulled the pump again and this time discovered a small tear in the fuel hose that connects my fuel pump to the line (i had to make it like that bc i lost the gasket that sits in between them and didnt have a reason to buy one when i can run it like a 2nd gen fuel pump (thanks kevin) well after i replaced that car started up and is now about to leave the driveway...

and this is for you kevin\/ there are 10 now...

Sweet! glad you got it running again.. no better feeling in the world then getting your car running after its been down..









sept for getting laid.

What's wrong with it now?

I think you seymour guys are a part of a conspiracy to maintain at least one "my car is torn up" thread in the FD section of this board at all times.
