    Grease, what ECM are you using? have you tried a stock prom? It won't run well, but should start.

    Hello I'm running $0D. 7427.

    Street fire coil, timing iis dead on put my finger over the #1 plug and cranked until it blew my finger out and lined it up to 0 degrees,

    it could be 1 of 2 things.....IAC. I did the reset tbi test and IAC did not extend or retract found two blue iac wires A-high/Low the voltage was reversed coming out of the ecu per the schematic realy weird.. I do have the 454 iac adapter plug..

    also I bought a cheap $60 Efi distributor off of eBay..

    Engine was trying to start sounded like only 4 cylinders were firing and then a loud backfire. Any ideas where I can search for what

    tables,to change a guide if you will for a 383 with 454 tbi? Any help is greatly appreciated...
