Shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.

Equipped truck with remote start/ custom security system. noticed about a month now that it sometimes wont crank on first two tries wether by remote start or by manually turning the key. had to jump start on couple times. recently while driving it completely shuts down. dash board lights up- traction on/off, security flashes, abs, low fuel, shift selection gone, parking brake and more. i ckecked fuse compartment left of steering wheel and found no blown fuse. i checked fuse box under hood and found ECM1 FUSE blown. i changed it and truck fires up fine. i drive home. next morning i had to jump start battery which fires up on first crank. truck drives for about 4 miles and shuts off. check for blown fuse, ECM1 is blown however this time upon changing the fuse and crankiing the vehicle the fuse just keep getting blown. i went through 5 fuse. my fuel pump will not prime when i turn the key to on. i took out the fuel pump relay, try cranking/ turning the key to on to prime fuel pump and this time the ECM1 fuse stays in tact. got new battery still no good.

Sounds like the fuel pump is shorted.

Where is the fuel shut off switch in my 2002 mazda 626

Your vehicle does not have an impact activated fuel shut off switch like the ford vehicles. Power is provided to the fuel pump by the fuel pump relay. Power is provided to the fuel pump relay by the Main relay. Both relays are controlled by the Engine computer or PCM. The PCM can disable the fuel system by not energizing the fuel pump relay if the immobilizer system has been triggered by the use of a non-authorized ignition key being used to start the vehicle. This should also trigger the security light to be flashing on the instrument cluster as well. Look for that rapidly flashing security light to see if this is the problem.

2003 chevy silverado 5.3 will crank but not start and has no power to the pcm1 fuse

What make vehicle ? You need to find a power distribution chart an see where that fuse gets it power . Some vehicles have a relay that powers up the vehicle . ford has power hold relay , gm on some models has a run / crank relay , Chrysler has ASD - auto shut down relay , Asian vehicles have a main relay etc... But as long as there is no power to the PCM it's not going to start !

My 2002 gmc envoy starts with remote but will not crank with keys

The remote start bypasses the ignition portion of the antitheft security system to allow you to remotely start the truck. But the system still needs the signal from the key to allow the vehicle to remain running and drive. I would assume the ignition is bad or needs to be trained to the system if it was replaced.

Did you check the fuel pump relay ? The relay gets power from a fuse and also from the PCM relay. The computer grounds the relay to turn it on for 3 seconds when you turn the key on, then only after the computer "sees" RPM or oil pressure.
