Question about 1999 GMC Suburban
I have a dead miss in two cylinders in my 1999 GMC suburban, Ive replaced the fuel pump,spiderinjector with new plentum gasket on upper plentum also replaced the fuel pump 52psiat gauge. Ive changed the plugs today it runs a little smoother but still mssing through complete range.I plan on changing wire set tomorrow.any suggestings?
Check the firing order for starters as 2 crossed wires give a symptom similar to yours. Have the fault codes read first as that can save you real money in finding the fault. Have a compression check done to eliminate a blown gasket between cylinders.

Are you talking about the check engine light? If so it needs to be reset with a code reader. then if it re illuminates you still have an issue.

It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.

if you say you replaced the fuel pressure ? "regulator or pump" that was not very clear as to which so i am guessing and the filter but have no fuel to the fuel bar valve either you have no power to the pump or a clogged fuel line or a blown fuse or a short in the power suppluy to the fuel pump if you turn the key to on position without cranking it do you hear a slight humming noise if so the fuel pump is working ..if you do now hear this chances are as i stated above
the use of a test light is required to check for power to the pump as wel do you smell any gas =fuel lines are rotted .let ne know what you discover and check all your fuses
