To start out the car is a 1997 Spyder GS-T with a 16g turbo.
Almost entirely stock besides the 3” exhaust from down pipe and the 16g turbo. Around 140k miles. Motor was recently rebuilt. Car sit for 5 years before I bought it, plus it’s been sitting 8 months since I’ve owned it. Since then I have put over 8 gallons of fresh gas in it. The tank is almost full with new gas.
A little while ago I posted trying to figure out what was going on with this thing ever since I got it put back together. I’ll list everything I’ve checked and go from there.
Air: Almost everything is brand new except the SMIC and MAF sensor.
Fuel: I was having fuel issues that I was able to fix. Now I have consistent gas to the injectors and they are all pulsating fine.
Spark: I have checked the gap on all 4 plugs. They’re all at .31.
Also checked spark by holding the plug to the valve cover and checking for spark. All 4 have spark.
Timing: I have checked Timing and all 4 line up. Will include photos.
Compression: I checked Compression across all 4. I am unable to get a warm test, because it will not start. But the numbers were consistently around 141-150.
Firing order: I currently have the 97 ECU in the car. I am using this diagram to run my plugs.
Crank Sensor is brand new. I have flipped the CAS sensor both ways and neither really changed anything.
I have 2 ECU’s one is the stock 97 ECU which I was told may be bad so I bought a 95 EPROM and that didn’t change anything. Both pass the CEL test.
I will include 2 videos.
The first one is without starting fluid. In the video the car fires but immediately dies. It wants to run but something is preventing it.
The second one is with starting fluid. The car will run for about 10 seconds with starting fluid. I am able to rev the motor, up to about 4k rpm but then it dies.
I’m at a loss now. I’m hearing a few different guesses.
1) MAF sensor is bad
2) Fuel pressure (It comes out like a hose pipe, consistent, but it doesn’t spray extremely hard pressure)
