I'm having a problem with my 88 305 .Its really had to keep it running when it cold if i keep the maf hooked up, I've checked the cold start injector and it's spraying at start up. i adjusted the tps to 0.5v at idle position and 4.9 at wot, the Iac vavle is set to 1-1/8" The 8 injectors all read about 16.7 to 17 on the ohm meter,I haven't checked if the injectors are bleeding down with a fuel pressure gage because i don't have one. I don't smell alot of gas when it does start. Its seem like it's running out of gas.It will run for about 5-7 secons at 1100 rpm then dies.If I keep pumping the throttle to keep running until it warms up it's fine but that takes about 4-5 minutes to do that. Should i check the regulator and how would i do that? Any sugggestions would be greatly appreciated.

 

Did you ever figure this out? It's no joke exactly what my GTA is doing to me right now.

 

fuel filter might b clogged. check the fuel pump pressure.

 

Have you replaced the maf sensor relays yet? You said it will run with the maf unplugged
I'd try new relays.

 

Haha oh ****, I already bought a new used MAF. I never even thought of that damn relay! Because mine doesnt even throw a code, but she runs great with the MAF unplugged.

Think that's the relay?
