1989 Jeep Comanche - Crank but won't turn over.
fiatslug87 replied to dotnetrob's topic in MJ Tech: Modification and Repairs
That’s a weird gurgling sound. You can pull the fuel line from the filter, put it in a jar and try starting, see if the pump is delivering anything. Or just pull the pump to see if everything is connected and bench test it. -

I would leave the CPS alone, since it starts and runs with starting fluid it’s getting spark. Concentrate on fuel delivery. The TPS should be at 17 at idle when you get it running. -

By turning over you mean it started and ran for a second, right? Jump the fuel pump ballast resistor on the driver side fender and try starting. You can also check fuel pressure at the rail, Cruiser’s tips has the procedure. -

Will it start if you put starter fluid down the TB? -

I remember someone wanting an original hard copy of the fuel injection manual, there’s one on eBay LINK. This is the same as the one circulating with a different cover and a missing page.

According to Cruiser’s tips 0.3v is too low. https://comancheclub.com/topic/73466-7-–-cps-testing-and-adjusting/ -

Then check the CPS as stated above. Sometimes if you disconnect and reconnect the CPS it fires up. -

Do you hear the fuel pump prime when you turn the key before cranking? -
The one that’s just above the oil pan (driver side) is the knock sensor, the one farther up and back is the coolant temp sensor.
