Try and get a scanner on it and see if you are reading rpms when cranking, also.
Maxwedge,

Thanks for the reply! I asked for some help on another web site as well and a guy responded with very similar advice to yours. He also mentioned a noid light and the PCM. Did you mean the PCM or is the ICM something else? I found a noid light for $6 so that's not a problem, but what is the PCM and/or the ICM? He said that I should check the throttle position sensor first. According to him it had to be the TPS or something to do with the PCM. If the TPS checks good but no joy at the injectors with the noid light then he said the PCM. What kind of scanner are you referring to, is it something one could buy? Do you think the earlier symptoms when it was still running are related to it refusing to start now?

Thanks again,

Jim
