Car hasn't started in 3 years. Due to bad ignitor & relay. The gas was mostly taken out so it had a little bit in there. Added about 2 1/2 gals of fresh gas. Changed the spark plugs fixed the other issues and now it starts. The car was tuned before so it was running fine. We thought the CAS (the connections on the tail harness went out to being part of the reason the car never started again) was also bad but it's actually not and reset the timing back to TDC. Not sure if it's still a timing issue or a bad gas or maf. Any ideas?

This is with me giving it gas and the car will only rev up to about 2k rpms.

Im gonna try and change out the maf with anoother z32 maf and see if that helps at all but any other ideas would be great. also it could be a tuning thing and if so thats an easy fix but i dont think thats the whole problem.

her is a Vid of how it sounds

Start with all the usual suspects. It sat for 3 years so I wouldn't be surprised if your IC piping couplers are rotted/torn/chewed up. Also wouldn't be a bad idea to pull the valve cover off and make sure at least everything on the top end is all in order, like rocker arms not being broken and things like that. Get back with results.

gonna take out the fuel thats in there tonight and add in new fuel...... I guess the mixture might not have dilutted it enough. also getting a new MAF to borrow and try. i will let you guys know tomorrow...... as for the rockers and such. when we TDC it we also looked over the heads everything looked to be ok

Update. Maf is good. Changed out the gas so that is good. But on the bad side we popped another fuel pump relay that's 3 times now we popped it.

try o2sensor if it got muffed up due to bad gas and non sense but sounds like the car is in limp mode i have a rom tuned sr when it is limp mode useally means the chip burnt out or maf/o2 sensor is bad unplug o2 sensor and run car to see if it runs better

Are you fireing on all 4 cylinders. I would say that the injectors are clogged or gummed up. I had the same issue with my last sr. Changed the fuel pressure regulator didn't change anything swaped the coil packs around still same. Got new injectors and o rings and it was gone.


Hope this helps

@ s13 mike. I'll try it.

@ Dan the car idles perfectly fine & starts fine. Only under throttle it starts to break up. But in willing to try this out. I gotta see if I can find the stock ones or borrow a set. I did test the inj before by unplugging each one and when I did this the cars idle would change.

seafoam it?

UPDATE!

CAR RUNS!!!! for the breaking up it was the CAS! it had enough juice to start the car but that was it! switched out another one and she runs great!

Thanks for the help everyone
