A week my truck was starting up and running ok it has a stock chip flashed! I ordered a new after market chip, but in the mean time i went away for 3 days came home and the truck will not start: i know it has fuel pressure, coil gets spark and distributor is getting spark! Im sure i have compression! I changed the ignition module yesterday and still nothing it just cranks and cranks... please help:roll:

Does the tach jump when you crank it over?

Yes! And i just checked ecm fueses as well as all of them! Could it be ECT sensor? Or is my ecu and or chip fried?

Not trying to be a smartass but does it have gas in the tank?

From what I gather it was running,you didn't do shit to it and now it won't run?

Re: NO START On sy

MySY does this when I let it sit. Myself I try starting it a few times. When that dose not work I disconnect the Fuel relay and crank it over a couple of times tel it acts like it wants to start. Then I plug in the relay and start it right up.
 
Re: NO START On sy

Its possible some critter could have gotten in there and chewed some wiring, have you checked the wiring around the ecu and inspected the rest of the harness for damage?

It all looks ok for the most part, but if new ecm and new chip dont work i will be tracing every wire >_<

If the check engine light comes on when you turn the key on the ECM is prolly good.

You can check that with a paperclip. Flash flash flash is working fine.

Re: NO START On sy

still nothing...just cranks fast and rpm gauge is moving fast wen cranking
wont start still..new chip new ecm just cranks fast! i tried putting new rotor in and it acted like it wanted to fire and i then changed cap after and then it acted like before just cranks fast! i put a new ign control mod in from az last week idk if they rly could of sold me a bad one but coil is getting spark and so are plugs..plugs are a little foiled out from being so rich when it was running but i think it should still start just run like crap...i read on some s10 fourms it could be ign switch under coloumn but idk about that! do sys have ckps? im so stumped?

Re: NO START On sy

Have you verified proper ignition timing? I.e. Zero degrees top dead center with tan wire disconnected? Maybe your timing chain walked a few teeth.

If you have spark at the plugs, fuel at the injectors and compression it should run, is the timing right other than that sounds electrical, if you spray some fuel in the throttle body does it try to flash ?

Also pull your ECM fuses and check that they are not corroded, had that sting me once, fuses tested good with the test light but I pulled them out and it looked like they had got wet at one time (mustang tears) replaced them and it started right up

i checked the fuses they are o.k..the last time it was running i had the timing set at 0 and since then i didnt touch it and it was running...went away for 3 days came home to start it and nothing began this cranking but no start problem! im going to try new plugs tmr and hope for the best...s10 guys some say it can be ign swtich under steering column but i dont think so! im so upset and confused like wat can it be! im going to check compression also but i dont know what could of happened in 3 days
