So like the title says my 94 gs will not start.... I have fuel pressure at the fuel rail, I'm getting spark and all my timing marks line up correctly. so I'm out of ideas. the starter is engaging and turning the motor over but there is no attempt to fire.
CEL? Any DTC? Blown fuse(s)?
are all of the wires to the fuel injectors connected?
have you attempted to start the car with your foot on the gas? if you can, this would be a dirty throttle body, or, your MAF (I don't know if you guys have one, just throwing it out there) isn't connected or you have a bad connection to it, which in any case will cause a check engine light
cel is clear. its not getting fuel from the rail to the cylinders... i get plenty of fuel at the rail and in the return line, pushing the gas peddle changes nothing. fuses are all fine as well
its probably the injectors themselves, have you checked those?
Did you change your fuel filter it could be clogged?If you changed that recently then i would say it sounds like your fuel pump is bad.
Here's what I think...
1. Distributor
2. Spark plug wires
3. Spark plugs
4. Battery
5. Fuse. Or short.
Easy way to eliminate 1-3 is to pull spark plug out attach to wire an see if u get spark
Eliminate 4 replace battery or jump ur car..
Eliminate 5. Check um all lol
Has the car been sitting? Maybe from sitting the gas has too much water in it if it was.
Also the GS has coil packs and a power transistor not a distributor
I would add something to remove any water that has gotten into the tank as this happened to my girls BMW a couple months back. And then we can go from there
its my DD so it is driven a lot, i was out running around and parked it and when i came back it started what its doing now. I have verified spark in all cylinders and fuel pressure and flow to the injectors but its not getting through any of them. I think the chances of all 4 injectors going out at the same time are astronomical at best.
Edit: I grabbed my meter and checked the injectors. I read 14.6 ohms in all 4 injectors
So it has been driven? I thought that it did sit for a while tho. Maybe some injector or fuel system cleaner and see how it goes.
It has be the fuel pump then,do you hear it come on when you turn the key on?
I pulled the fuel supply line and filled a jar with fresh fuel when i turned the engine over. the fuel is only a week old i drive the car everyday
there is supposed to be 50+ psi of fuel pressure. fuel could be new but bad as well. thats what happened to the BMW
What octane of fuel do you run in it?It is possible that you could have bad gas,try the fuel system cleaner like galanttuner10 said and see if it helps.Quote:

ya it would be astronomical for them all to go out but its possible they all might not have been working right while you were driving. when u were driving it was there anything unusual happening??
Hmmm...try shooting some starter fluid or something similar in the intake and have someone turn over the engine. If it starts then its fuel related: Is fuel pump pressure above 45psi? Is the injector receiving their signal from the ecu[use noid lights, they are your friends] Is the motor 20A fuse blown? Clog fuel filter
No CEL so look at a possible camshaft/crankshaft sensors as well. Also, dose the CEL stays on when the key is in ON position or flash when you grounded Pin 1 on the DLC?
Sorry for the super quiet sound quality but this is what I'm getting.

I hooked my meter up to the injector harness and got 1.56v DC with max hold while cranking
i dont know man it has to be fuel related,pull off the intake spray throttle body cleaner or starting fluid in it and try cranking it over and see if it starts.
ya it turns over if a crack baby it lol and i'm getting fuel at the rail and the injectors and wiring check out, i am so out of ideas its not even funny. I'm to the point the stealership is sounding like a good idea
You did the spark test and had spark right?It really seems like the fuel pump,i would try the test for that first before you take it anywhere.If it starts on that then it has be the fuel pump.Quote:

I thought you meant test the fuel pump.... spark was the first thing i checked. but I get plenty of fuel up to the fuel rail.... even if the fuel was under 45psi i should still get at least an attempt to fire. the fuel pump seems to be cycling fine
I dont know was the car running fine the day it happened?You didnt notice anything strange or anything.
Try a known working cam angle sensor
or
Try a known working MAF
Sounds like you have spark and fuel so its time to check other things that contribute to the motor running.
cam angle sensors on the GS suck, they are under the cam gear. its def something electrical or water in the gas. i hope its nothing electrical esp not the cam sensor
does the fuel pump send fuel if the ecu doesn't get a reading from the cas
should still pressurize but nothing will spark if its the CAS
well I have plenty of spark
