1996 Jimmy won't start in cold
#12
All this happened the morning after I replaced the starter. I'm thinking coincidence. But It is possible I messed something up.

I'd check engine temp / coolant temp and intake air circuits.
Since you feel this problem began right after the starter R&R look for any broken or disconnected vacuum lines, esp. to the emissions systems if you're getting a DTC for it.

Funny you say this because temperature gauge in truck didn't get over about 120 degrees today. Needle barely rose. Once again I had to roll start the truck also.

Got a tip I could have a leaking injector. I looked into the throttle body and looked black. Except on the right(drivers) side there was a little gold discoloration. Carbon looked slightly thinner in fact. Possibly some washing. This could be my problem? if so what actions would I take?

Truck left me stranded yesterday so I had to put it in the shop. Got a call today and was informed that the truck is getting good fuel pressure and spark. Mechanic says he knows for sure that my MAF is out(short) and is causing my problems. $250 quoted for parts and labor. Diagnostics work is only 50 bucks so I'm picking up the truck and replacing the MAF myself. Would anyone recommend aftermarket? I could easily go to the local junkyard and get one for about 10 bucks.

Glad you know the problem.

Did they say if they retrieved any MAP DTC's? It's not impossible, but rare for a MAF sensor to cause a no start. The only DTC's that you retrieved before were EVAP problems, and they definitely will not cause a no start.

i don't think its a MAF sensor problem(i have been wrong many times before though), and positive its not a EVAP problem. Im thinking ignition switch, its common for them to be cranky(pun intended)
