Whitaker717 Posted September 28, 2021 Share Posted September 28, 2021 So I am brand new to the Comanche world. When I go to start it, cold or hot, it takes about 3-5 revs before it kicks over. Can someone tell me if that is normal for these Comanches. All my other vehicles crank right over. They also are not 34 years old. Thanks guys Link to comment Share on other sites More sharing options...

Whitaker717 Posted September 29, 2021 Author Share Posted September 29, 2021 Thanks Eagle. I’m just used to my trucks firing right up. Link to comment Share on other sites More sharing options...
Minuit Posted September 29, 2021 Share Posted September 29, 2021 The Renix computer requires either a certain RPM or all of the relevant sensors to "check in" for a certain time, I forget which, before it will allow the engine to start. Either way, it's normal. The High Output trucks start a little faster. "neer-neer-neer-neer-VROOM". If it ever takes more than about 3-5 revolutions for the truck to start but it does start eventually, that would point to a fuel pressure retention issue.

Whitaker717 Posted September 29, 2021 Author Share Posted September 29, 2021 That’s definitely mine. About 3-5 revs then he kicks over and purrs like a kitten. Silly question but is there a way to speed up the crank over? Link to comment Share on other sites More sharing options...
cruiser54 Posted September 29, 2021 Share Posted September 29, 2021 Possibly. Have you visited my website? Link to comment Share on other sites More sharing options...

Silly question but is there a way to speed up the crank over? What do you mean "crankover"? Cranking is when the starter motor is spinning the engine. If you want a faster crank speed, get a fancy, high-dollar starter motor. If you mean the engine actually starting, that's not "crankover," and if it starts within about 5 revolutions that's normal and there's no way to make it start sooner.

Whitaker717 Posted September 30, 2021 Author Share Posted September 30, 2021 Just wondering if there is a way to make the engine turn over faster. Sorry about the terminology, I’m just not that car savvy. At least yet. Link to comment Share on other sites More sharing options...
Minuit Posted September 30, 2021 Share Posted September 30, 2021 Sometimes a starter can fail in a way that it cranks, but very slowly. That happened to my original starter. This can very easily be confused with a dying battery. Make sure the large cable leading from the battery to the starter has clean and positive connections at both ends.

cruiser54 Posted September 30, 2021 Share Posted September 30, 2021 and if your starter is covered in oil, it's likely slow. Link to comment Share on other sites More sharing options...
