big66440 Posted March 11, 2011 Share Posted March 11, 2011 My 89 comanche 4.0 has a problem starting when it's dead cold,I've thought of checking the coolant temp sensor to see if it's within range or maybe the TPS sensor isn't calibrated properly (engine was rebuilt less than a year ago),the fuel pump is new and I haven't had time to spare and really look at the components,also is there any way to make the engine start quicker rather than the long cranking that 4.0's do before they start?

NewfieMJ Posted March 11, 2011 Share Posted March 11, 2011 Could need a tune-up Could be a weak coil Could be bad caps in the PCM Could be a fuel line issue(leak or kink) Could need a fuel filter Could be a weak starter motor I moved my donor a few days ago in -20C (4.0MJ), it took 4-5 secs of cranking and been parked for a week or more . The starter was slow , only for that I bet it would have caught in a sec or 2 Link to comment Share on other sites More sharing options...

Dirteatr717 Posted March 11, 2011 Share Posted March 11, 2011 Leave the key in the on position so it pumps the gas in... Usually helps mine start a tad quicker Link to comment Share on other sites More sharing options...
