I've noticed this happening the past week. I will drive my truck all day. And Randomly my truck will just stall, no warning, nothing, this happened te other day as soon as I got off the highway it turned off. I've noticed when I run heat or hit my brights or turn on my lights my battery meter moves. My guess is the strength of my battery. I drive in the morning and the heat cfm lowers at Idle., when I hit the gas the speed moves up, and the truck takes a few tries to start up again, I'll pump the gas pedal and everything. I threw my meter on and I have 14 to 15 volts while truck is running. I don't know what else it could be.
Ok I'll look for that, last night I went up to autozone and was asking around there to, my alternator is only putting out barely 8v ripple, whatever that means, and all of the tests they run my truck passed them. He said tomorrow we can check your fuel system pressure, I didn't know they had the tool for it, I guess that could be a problem to.
He had me try and start it and my truck didn't start again, I tapped the gas a few times, kept trying and kept tapping, and eventually after a while it started, both autozone guys said raw gas was burning up, so I am getting fuel I think
Another possible cause could be the ECT ( ENGINE COOLANT TEMP ) sensor which tells the ECU how much fuel to supply to the engine i.e more full on cold start and then leaning out as it warms up .
The previous owner put an aftermarket sensor for the temperature in, both gauges do not work in my truck, he also bypassed the throttle body, the auto zone guys said that heats the truck up faster. Can I test the sensor?
Thanks and it's not for my vehicle, I wonder if the voltages and resistance are different. Just got home. Drove my truck all day long, and an hr and a half haul and within the last minute of our trip it cut out, pulled off the road and didn't start. Pumped the gas, turned, nothing, tried for 5minutes and eventually started fine.
I replaced the battery today on a side note, starter wouldn't turn over, and I couldn't jump out the starter solenoid on the fender wall, it wouldn't do anything no sparks or anything. But starts fine now. Have a good battery
The specs for the sensors are all pretty much the same, it's how they're attached to something that changes. Can you clarify something for me? Did it still have a problem initially after changing the battery and now it starts fine, or did changing the battery straighten things out in the starting department?
