Check the fuel pressure you need 13psi to 15psi, anything different you will not get a start. The other thing to that is common to fail is the Ignition Control Module (ICM), IT coast around $40,00 at Auto Zone and they can give you the step by step instruction to getting the job done with common tools. Good luck and keep me posted, be glad to help.

06 Chevy Trailblazer cuts off while I'm driving, cranks right back up

Possible a charging problem, dirty battery cables. Does it completely stall out, quit running? Ground wire to computer. If fuel pressure is good, Did they test drive it and the pressure stay good? Have you changed the fuel filter? Several possibilities.

My 1997 chevrolet suburban will crank up, but when it warms, it cuts off and I have to floor it in order for it to crank. Then while its running it hesitates and runs bad. What is the problem?

Possibly fuel filter needs replacing. If fuel system is not getting enough pressure it will not start or will run poorly.
Also may want to check distibutor cap and rotor

Havig trouble with maintaing speed

The electric switch is for the downshift solenoid on the 400 turbo. It will work with out it but you will have to downshift the trans manually. When it dies does it act like you just shut the key off or does it run bad first?

92 Chevy Suburban Electrical Fuel System

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.
