i have an 88 cherokee and while im cranking it over it was almost seem like the starter dies then continues cranking.... or the engine will hicup while its cranking.

once it gets started it runs fine...

brand new blue top battery, brand new starter, brand new coil, brand new cap, plugs are fairly new and wires are new.

oh yeah its a 4L renix

 

Hiccup?



Try scaring it or a glass of water always helps.

 

will it hicuup and than start right after?

 

Usually when I hiccup I start again in like 10 seconds.... then 10 more seconds.


Very annoying

 

Maybe some screwed up teeth on the flywheel or flexplate?

 

it will start but every time it cranks it will choke or or hesitate but eventually start

when it starts it runs great

 

upp

 

upp

 

I dunno which is more funny. Your answers or the OP ignoring you.


OP, what have you done to diagnose? Have you changed your plugs and wires recently? Hows your air filter looking?

Does it still happen if you let the key sit in the "on" position for a few seconds before cranking it?

 

air filter is new, ill let it sit and it will be the same...

all vacuum lines are new.

 

Almost sounds like you lose fuel pressure when the truck is off, but I'm not sure. Have you done anthing else to diagnose?

 

the pump is new and i dont have any fuel leaks...

im still out of ideas

i have been checking wires all day and still have the same issue.

 

How is your oil pressure?

 

oil pressure is fine.... i was just thinking could it be my check valve gone on the pump assembly? maybe all the fuel is leaking back into the tank?

 

Your Jeep has a guage for oil pressure or an idiot light? Just asking because mine was hard as hell to start and my oil pressure was reading maxed out. Blew my oil filter off and did other things I havent figured out yet.
