Intermittent Crank No Start After Tbelt, Water Pump, and Starter Replacement

[WhoIsTwon]

Having intermittent crank no start issues after replacing timing belt, water pump, and starter. In the morning when it is cold fires up first try no issue also after stopping for a minutes she will fire right back up again with no issue. The crank no start seems to happen most often about 1-2 hours after parking. Then you get in and it will just keep cranking strong but wont actually fire. Security light goes out when key is inserted so I do not believe it is an immobilizer issue.

Any thoughts or ideas about what it might be would be greatly appreciated.

Miles and year? Could just be the fuel pump and coincidental timing.

2000 with 215k miles

Adding that when it does fire after sitting for some time RPMs seem low almost like it wants to die. Wondering if it is a fuel pump issue.

there are known immobilizer issues with melted contacts in the fuse box in early 100 series, not sure if this affects 2000 model years

I had the same symptoms today....after the same service. Mine cranks easily, but will not start. Tomorrow and will check fuel pump circuit and any relay. It would hazard a guess that is your situation. I actually had a Honda with a bad fuel pump relay. It would get warm sitting for a short period of time and not function. If started cold, or afer setting to dissipate heat it would start--bad relay.

I had this same issue and did the exact replacement maintenance you mentioned. Definitely replace the fuel pump, while you’re at it replace the fuel filter as well, maybe just for the heck of it get a new OEM starter relay as well!

What are the chances that 3 timing belt replacements lead to fuel pump failures?

Also: why would you replace a starter relay if the starter is cranking the truck over fine?

Don't parts cannon these things. If you did timing belt system work, was your timing dead on? That's where I'd be looking first before assuming other parts not associated with the work failed.

Fuel pump or filter, would not be affected by the above services.

Checking fuel trims, ECT and coolant level along with visual inspection of engine, is first step.

With timing belt service. Issues I see after:

• Cam sensor wire housing block (plug) loose. Not properly locked/click together.
• Cam sensor, bolts not properly secured. (some remove sensor, I don't)
• Wire harness for crank sensor and oil sending unit, routed improperly. Wires rub on serp belt/pulleys, cutting wires.
• Crank sensor wire housing block (plug) loose. No need to release this one, but some do. IDK why.
• Coolant level low.

Intake manifold removal, issues as a result of R&R:

• Dirt/sand drop into heads intake ports. Due to failure to clean top of engine.
• Intake manifold gaskets not replaced or installed wrong. Vacuum leak.
• Intake manifold not torqued down. Vacuum leak.
• Throttle body gasket leak. Vacuum leak.
• Vacuum line(s) not attached. Vacuum leak.
• Fuel delivery or return hose(s), clog or kick.
