[turbotyla]

Ok so i got my comanche its a 87 4.0 renix

 

when i try to start it it takes a little bit of cranking to start is this bad. My motor worn out or just need some part. ?

I checked fuel pressure and it seems ok.

 

And when i am driving in 5th gear going down the highway around 2,000 rpms it acts likes its missing and shuddering.

 

i have don't new plugs,wires,rotor,cap,oil change, new idler pully, new serp belt.

Any help is much appriciated

A long crank time is typical for renix trucks. As long as it's consistent in its duration and reliable in operation, I tend to ignore it.

my 87 4.0 does the same thing. pretty standard for them. my 92 4,0HO did it as well
