Barely wanting to start

[Kendall88]

When I try to start my truck which is a 2000 Dodge Ram 5 speed. When I press the clutch in to start it it will barely start. It will take a good minute to actually start. I was wondering what it could be I know it is a v8 magnum the transmission I am not to sure about any info will be greatly appreciated

Little vague. Does the engine crank over weakly or does it crank but take a while to fire?

Sounds like fuel pressure.

It will turn over but it takes awhile to fire

Sounds like fuel pump to me too.

Test fuel pressure at the rail. Should be around 49 PSI, the closer the better.

Also, when you stop cranking, the fuel pressure should drop SLOWLY. If it drops to zero right away then you've got a leak somewhere, probably a stuck open injector.

Weak pressure isn't necessarily a bad fuel pump. A faulty or plugged regulator can cause issues as well. However, since you have to remove the pump in order to replace the regulator, I'd just replace the entire assembly. It's not cheap, but removing the pump is kind of a PITA. I'd rather just replace the entire assembly once and not have to worry about anything relating to it for a while.

Can't replace just the regulator. It's all a single assembly and cam only buy the assembly
