No Fire

Started a new thread because my problem with dead cyclinders was fixed with opti. Tried to start and the engine cranked but no start. Check for spark at plug wire no spark... A few minutes later I was going to check the ICM while cranking but now it wont even turn over. WTH... Please advise Checked it for codes, there are none. The abs light is on in dash cluster but thats it. Fuel pressure is at 47.

Re: No Fire

Does not crank (starter engage?)? Check your battery and battery cable connections.

Re: No Fire

Weak battery, corroded terminals, corroded/damaged cables. What does the dash volt meter indicate when you turn the key to "start"?

Re: No Fire

Had a couple of things wrong. First off the no spark problem was the ICM, got it replaced. On the no crank issue, I haven't found exactly what is causing it. I'm gusessing either it has to do with the way the ignition swith is mounted to the steering wheel, (the switch can move forward or back slightly. Could this possibility be the problem?

Or my other guess is the clutch pedel sensor is not contacting the pedal all of the time for what ever the reason. The no crank issue in intermittent and is working now. Just wanted to know your thoughts on what to check so it won't keep happening.

Oh yeah battery and connections are good on both battery and starter.

In addition, now that I have replaced the ignition and the ignition lock cyclinder the secruity light is lit up on the dash cluster. Whats that mean?
