What does a Chevy 2500HD, A 50ft Tow Strap, and my Truck have in Common?
Well getting ready to leave work today and I start my truck, put it on high idle. I let it warm up and then I went to drive away. Well I drive about 50 yards and hit a stop sign and then I give it throttle let off and BAM!!!!!!! Engine RPMS go from 1200 tried to stay at 675 and then 400 and died. All in about 2 seconds. Dead wont start.
Well I have noticed similar things over the past few days. Like truck running like junk when cold. If you gave it throttle and let off RPMS would hit 500 ish (sounding like it want to die) then come back up to around normal idle 675. So when it was cold I would just take it easy. So thinking this was not normal, I decided to check FICM voltage and a good steady 48 DCV. So then I figured well hell, it has just got to be that it is cold and needs to warm up ~RUNS FINE WHEN WARM~ no problems at all.
So next idea is the "stiction" the case of oil causing the injectors to not fire right due to oil being so cold and not working right for the injectors. Well I run Rotella T5 systhetic. So figured not that, and just said "oh well just if it is going to run like junk when its cold, it will."
Ok back to Paragraph 1. After it died I pulled over and of course a few bad words and beating the dash. Well tried to start it and it cranks hard. Sounds like it wants to fire but doesnt. Climbed under the truck no fluid anywhere. Coolant level is steady and has been. So tried again. Same thing wants to start but doesnt. I noticed the oil H-L guage on the upper left of my cluster, well it took a while for it to get to the middle. (dont know if that is oil pressure, high or low?) Well after four tries I gave up and got a tow from a chevy 2500hd using my tow strap. Now I sit at my house with NO CEL, No DTC codes (using SCT). WHAT DO I DO? WHAT DO I CHECK?
