Hey guys, looking for some input. 98 GTP
Car stalled, wouldn't start back up. Would just crank and crank. Got the car towed home, had the battery and alt tested, both good. Car started after sitting for about four hours. Took it for a ride, about 2 miles, all seemed well, but when I pulled in the driveway, and left it running while I cleaned up my tools, it stalled again and wouldn't start back up. I did notice that it drove just fine, but when I was coasting down a steep hill the rpms bobbed between 1000ish and maybe 700ish. Idled perfectly normal. Started up just fine this morning, but I haven't driven it. I have a P0102 for MAF low input, but I've had this code for about a month now, I was just putting it off replacing the MAF.
I think I have it narrowed down to the following:
-bad MAF
-Crank Position Sensor
-Fuel Filter
-Fuel Pump
Anything else I could possibly check? Also, if I start it with the MAF disconnected, will I be able to drive it? I'm trying to figure out why it would start with the MAF unplugged, but not start with a bad MAF plugged in.. if that makes any sense. I'd like to eliminate that as a possible reason for the no start.
And as far as the CKPS goes, I was reading that a test for that is spark to the coils. I definitely have spark at the coils. I haven't been able to recreate the stalling condition to notice if the RPMs drop to zero, but other than the spark, it sounds like a lot of other threads that suggest replacing the crank sensor.
I'm going to have to wait until next weekend to replace the MAF, but I might do the CKPS and fuel filter now to see. Any other insight would be appreciated.
