Hello everyone - hope all is well. I've got a problem with my B2500 (2.5 Ranger) and I need some kind help.
My truck is a 1998 Mazda B2500, 5 speed Manual transmission, with about 196,000 miles. Been running just fine until this stalling thing started.
Here's the symptoms: When cold, starts up, warms up. Once warm, it stalls. The engine will restart, may run for up to 30 seconds, then stalls. While driving, the truck will stall in gear, and feathering the gas pedal will get it to fire again for a bit. There is no "Check Engine Light."
My Actions:
1. Compression test is about 190 PSI on all 4 cylinders
2. cleaned MAF (no effect)
3. checked voltage and ohms at TPS (nothing out of ordinary)
4. Fuel pressure on the rail is 67 psi steady, running or key on
5. sprayed carb cleaner around engine while running and no effect on rpms
6. disconnected IAC when cold and the idle dropped about 500 rpm to 600ish rpm.
7. listened to fuel injectors - they are all clicking.
results:
no change! All above actions produced no changes. The truck still stalls with no load, barely runs without throttle play when warm. I'm stumped - and no check engine light!!!
Thanks in advance for your assistance.
