hello im having a problem with my trucks ecm.

recently I had a fuel pump replaced. I drove the truck for a month with no problems. This past sunday the truck would not start at all. I had it towed to a repair shop and they told me they had to replace the fuel pump again. So they replaced the pump again under warranty and also the crank shaft position sensor.

i got the truck back and the same day went food shopping. Returning home the truck shut down on me several times. I managed to get the truck back to the repair shop and they checked it out for me again and told me that the problem is the ecm computer. They say that when the truck is driven the computer gets hot and shuts the vechicle down.

ok, I know I must replace the ecm but the service number has been ripped off of the ecm. I tried to get the part with out the ecm numbers but parts stores tell me that there is nothing I can do with out the service number of the ecm.


i wanted to know if there is any other way I can get the service number so I can order the correct ecm for my truck?

Try writing down the entire VIN# and take it to the dealer, they should be able to set you up

I have had the same problem with my 99 tahoe.
Replaced,
Mass air flow sensor
Cam and crank speed sensors
Computer
Distributor complete
Fuel pump
Fuel filter
Fuel sensor
Idle speed sensor
I have check all of my grounds, battery, and charging system, all OK

And I still have the same problem,
Check spark when it starts to shut down. My tahoe still loses spark when it starts to die.
? After market alarm?
? After market stereo?
If you find any info please let me know. THanks

Anybody care to ask WHY, WHAT, IF & HOW? Instead of holdin a shot gun keep replacing parts?
How does these parts function?
Why do u replace these parts?
If all circuit grounds voltage under load is good?
What are the circumstances on what cpts must have in order to produce spark?
If replacement parts are tested n makes a difference in result b4 & after.

I bet the difference

Might want to try an ignition module. Sometimes when they get hot, they will short out
