    A Little background first. Bought the car running with a blown headgasket. Replaced the gasket and piston rings and rod bearings while I was in there. I've been through the no start list a dozen time. Timing is perfect. Cylinder leak down test came back good. Motor cranks over but nothing else. Checked spark with plugs out of the head. Tested coils for resistance. All good there. Getting 12v at the injectors and injectors click when bench tested. Tested fuel pump also good to go. Fuel filter not clogged. Resistor pack plugged in properly and tested good. Linkv3 shows good numbers for other sensors and ecu light goes off after 5 seconds and factory boost gauge centers as it should. Didn't touch the Cas while the head was out. I'm at a lose of what could be going on.

    Plug wires in the correct order? If you unplug the MAF sensor does the car start? That should put it into a limp mode.

    I havnt not tried unplugging the maf. Confirmed the plug wires are in the right order. Tested the pump by supplying it with direct power. I can hear it kick on then off when turning the motor over by hand. Starter went out trying to get it going. New one is waiting for me at work. I'll get it In tomorrow and pull the maf and try to start it on starting fluid

    Have you checked for spark yet? I see no direct mention of it, just coil and wire testing/verification...

    I've confirmed spark with my eyes. Coolant sensor reads normal in link. I'll get a log up as soon as I can get the starter in

    Starter didn't come in at work today so I was turning the motor over by hand key on with the coil pack unplugged and logging to see if the injectors were firing. Injectors are not firing and I'm now only getting 1.25v at the tps connector. Is it time to pull the harness and start inspecting it for shorts or broken wires?

    Unplugged my map, gm 3 bar, and tps voltage returned to normal both with multi meter and link. Using ecm gm maf cable. Sensor has gotta be bad.

    not starting with maf unplugged or starting fluid. here's a log of my start attempt. thanks in advance for any help

    it would appear i flip flopped the coils when i mounted them to a new bracket for mounting them with the cyclone. fired right up and ran great.

    Glad you got it fixed, I didn’t have much insight on it, but was watching, glad it’s taken care of

    Rule of thumb. If you messed with something and it doesnt run now. Go back to that item.
