LT1 wont start

[qwicklt1ws6]

headgasket swap complete, valves are lashed, intake is on, all sensors hooked up and no left over wires.

motor turns over, fuel pump comes on and injectors are firing. it has a new gm opti, with msd 6al, and msd coil. NO SPARK at all

Check your fuses?

[qwicklt1ws6]

the ac/cruise 20amp fuse is blown, could that be it?

[meissen]

Wouldn't hurt. Also - if you keep trying to start it up and the injectors are firing, you're likely flooding the cylinders. Try pushing the gas pedal all the way to the floor and then starting it - when the gas is all the way down the PCM turns the injectors off and tries to c lear the flood condition out.

Check to ground wires next to the coil on front of drivers side head. the large braided on also connects to frame by antilock brake unit.

messed aroundand moved the connections for the coil, Now i've got spark at the coil and plugs. but it still wont fire. hooked up jumper cables cause it seems to be cranking over too slow, scanmaster is not throwing any codes at all, and voltage was good, maybe its a starter

have you pressure tested the fuel pump it may still work but very weak...and you valve lash im pretty sure you could make it too tight see if air is coming out of the intake unlikely but worth a try. bad gas try some octane boost? idk just throwing some things out there....

Make sure to check for spark using a spark tester and not just a screwdriver in the plug wire. Check fuel pressure too at the rail.

[ba94ta]

i doubt that'll help when i got mine rebuilt i had them clackin and all loose until i adjusted them while it was running. and it only took 7 crank overs to get the air out of the fuel line.

[ba94ta]

it could be if you have them to tight valves will stay open some times im sure he has cranked it over quite a bit he said there was fuel aswell????

[Kwazrollinz28]

who knows at this point. cant do anything online, its easier in person.
