I have a 99 GSR turbo. One day i was just driving around and the car died. I mean, it just shut off like you turned the key...it didn't sputter or anything, just off. I have since been trying to get it started. I had the distributor checked and its fine, i changed the plugs and checked all connections, but still it wont fire. When i replaced the plugs, there was oil on all of them which we attributed to a bad valve cover seal/gromets.

The car has spark and the fuel pump primes. I dont know whether it is getting fuel or not for 100% certainty though. I think it might be something to do with the resistor box connections. I'm also going to check the connection of my conversion harness to my ECU.

Does anyone have any other ideas what i could check?

Thanks!

 

Have you even considered the timing belt? I mean, I know that seems like the obvious thing to do, but you didn't mention it.

 

yes i have...the timing belt is fine. The cams turn freely. Another thing we have considered is the possibility that it skipped a tooth because before this happened, i had a ticking in the head, but i thought it was just unadjusted valve lash. I had planned to fix that.

 

If it jumped just a single tooth, which I believe to be highly unlikely, it would still run. It wouldnn't run normally of course, but it would run. Check your fuel pressure, and use a spark tester too. That way you can determine for sure whether you're getting them adequately...

 

Ok. We will have to try that next weekend. I'm at home for the weekend, but i'm heading back to school (about 80 miles from my car) tonight.

Thanks for the fast replies!

 

I think with the timing belt jumping a tooth the car would still run but idle and run messed up. Have you considered the main relay??

 

no i haven't.....what would that effect and how would i check for it?

 

The main relay is supposed to make a click noise when you turn the ignition to on I think, but I'm not 100% sure. But I say start with the basics, fuel pressure, and spark tester.

 

ok well to clariy that then...it cranks and cranks, but just doesn't fire

also, i posted this question in the Forced Induction Forum as well...heres a link for easy cross-referencing

You said, "The car has spark." Generally when I refer to fire, I mean it has a spark. So, by "fire" do you mean start or a spark?

 

Ok...sorry about that.

The car has spark, but doesn't start. I meant start when i said fire

 

Now you have to determine how "healthy" the spark is... Is it blue, or orange?

 

it was blue

 

Without seeing it, and assuming that you accurately described it, then I'd say you're getting ample spark. Now, you go to the next question, what kind of fuel pressure do you have? That you can't determine without a pressure tester.

 

i dont have an aftermarket FPR....i'm still running the stock one. I would assume that at whatever stock is still...

 

When I refer to your fuel pressure, I don't mean your FPR, but the pressure in the system- is it ample? Your fuel pump can be pumping, but not pumping enough, not enough pressure. Or your FPR diaphram could have been ruptured in the FPR. Or your vacuum source to the FPR has been cut off somehow. The last two are somewhat unlikely, but possible. You would also want to take a noid light to your injectors to verify that they are working. And you said you had your distributor tested. Who did it, and how did they test it?

 

My friend Matt tested it on a car and it ran fine. Also, i do think the problem comes down to the injectors. I still feel like the problem lies in the resistor box. I'm not great at wiring and i'm pretty sure one of my connections is bad.

Also, i cant tell anything more than just by sound, and the fuel pump sounds the same as always. Same with the fuel line by the FPR.

 

Thinking... I'll think tonight, consult WorldPac community, and I'll let you know if I find anything.

***Whoa!! Someone on the phone with my shop owner with the exact same problem...***

 

alright...i really appreciate the help!

 

Check the connection to your map sensor this happened on my DC4. Not exactly the same thing that happened, but it wouldn't start, I just happened to lean over the motor, and put my hand on the connection when I got it started, and it died. Pulled the connection off, and the terminals were corroded so bad that one of them fell out. Had to put a new pigtail on. And that scenario doesn't just go for the MAP sensor, but all other connections.

 

i'll go try it...

 

Just trying to help out. It sucks being without your ride, and even more so when you don't know how to get it fixed, because everything that seems could be wrong, is ok.

 

yeah it does suck to not have a car...especially because my winter beater decided to break too. My little brother hit a curb with it and the tie rod let go on the interstate.

He forgot to tell me about hitting the curb....i found out at 80 when i went into the ditch

 

well i tried the MAP sensor, but its fine...still didn't start

 

check ur crank sensor...sound the same problem with my other hondas..i could be wrong..
