i have a 2000 s10 blazer and i have a issue where the vehicle will only crank. it was at a point where it would only run when it was cold now i get nothing.

things done,
fuel pump
filter
fuel pressure regulator
throttle position sensor
cap
rotor
fuel pump is getting 60lbs at start and 50 at idle
checked voltage on fuses and it is not getting any power to the ecm b fuse and many others.
tried putting a ground directfrom the battery to the frame and the engine.

does anyone have any ideas.
thanks,
james

 

ECM B should have power at all times. (incidentally that fuse provides power to the fuel pump relay) If it doesn't have power try cleaning the stud and nut that feeds power to the underhood fuse box, check for power there while your at it. Make sure battery terminals are clean and if you still have no power remove the battery and tray. On the firewall is a 175A fuse between the battery and underhood fuse block, use an ohmmeter or self powered test lamp and check it for continuity.

 

You really need to get a wiring diagram for your year of truck. It will be the road map to your solution!

 

have power to all the fuses and they are all good now, alternater was defective so i changed it.
tried computer
fuel pump
fuel pressure regulator
fuel filter
air charge sensor
cap, rotor
throttle position sensor
fuel pump relay
ground wire to frame
getting spark and it will crank but it will not run.
all ideas will help at this point.
thanks

 

Have you looked over Kyles https://blazerforum.com/forum/engine...not-run-45944/ ?

 

i was having a issue with my 2000 s10 blazer and i would like to say thanks to all the people that helped me repair my blazer.

the issue i found was the fuel inertia switch and the alternator had a bad stator but when i replace the fuel pump a few week ago i saw a connector that had the wires cut so i repaired them an now i know why they were cut bad switch.

 

Holy cow! Please stop guessing and replacing good part! Guessing is expensive! (Which im sure yuou know by now)

Troubleshoot the problem in a logical way.

Follow the troubleshooting guide. Since youre probably ticked off at this thing, I would start from ground zero. Look at stupid stuff. Like is the rotor in the distributor? (DONT ask why i make that point). Recheck everything, twice, and have a friend over to help check stuff. A fresh face is a great help. BUT dont let your friend guess what is wrong and spend your money!

Good luck! We have all been there.

 

What was your original thread?

Holy moly!

I was gonna say look for tripped inertia sw but I searched all over the place and diags and couldnt find any reference to it.
?????
Although I searched for 'fuel + collision + interlock' so that might be why.

First thing brought up in Ford forums.. "What did you throw in your trunk?"

 

I knew Ford had that switch, but if I had to look for it on my blazer i wouldnt even know where to look!
