Ok I just put the new fuel pump in bc I thought that was the problem, how do I fix the check valve? Also thanks to everyone and especially you allaro you've really helped me.

 

The check valve (one-way valve) is built into the fuel pump assembly. I know you just replaced the pump, but it sounds like it has issues. The check valve function is to prevent draining of the fuel line back into the tank when the key is off. When it leaks the line drains and then has to fill back up at the next start-up. This is the reason for the delay in starting...insufficient fuel at the engine.

 

In the morning, try turning the key to on for 3 seconds,(not engaging the starter), then off, then back on for 3 secs, and repeat this a couple times.

Then see if the van starts easily. If it does, then The check valve on the new pump assembly is questionable.

Perhaps there is a kink in a rubber fuel line at some point, or even a slow leak.

If doing this has no effect on morning starting, the problem likely lies elsewhere.

If the key on/off trick works, then the above gadget can be added to remedy the issue without dropping the tank again.

Something(excessive beer consumption perhaps) is making me think about the evaporative emissions cannister too. The charcoal cannister. Check the vaccuum lines running to it. On mine('89) the vaccum is solenoid operated.

good luck.

 

Ok so i turned it a few times before starying it this morning and priming it helped a lot so I guess we can assume its the check valve. If I buy the new check valve that landyacht suggested then how/where do I install that? Also what other options do I have?

 

I'm thinking that there is a possibility that there is a kink, or even a slow leak in your rubber fuel line close to the engine. This kink puts extra pressure on the fill side, and overnight it fights the check valve and wins. Or the leak simply relieves the pressure overnight. Note the gas would evaporate as quick as it would leak out and not puddle.

What brand pump did you install? I know the labor is not covered, but I'd make them honor the warranty.

I think the external check valve should be as close to the tank as you can get it.

 

I bought the oem I installed it myself so there's a warranty on the part. I'll check tonight for any kinks but how would I find out if it had a slow leak? Run it then shut it down and watch?

 

have you tried putting STP products into your fuel tank, they do a good job.
