I have to pump the gas peddle over and over to get it to turn. Usually takes about four tries, but sometimes it doesn't start at all. After it sits for half a hour or so it will start. What is my problem?
Pumping the pedal on an injected vehicle does pretty much nothing to aid in starting. Try either moving the pedal to one particular spot (experiment) where it starts or put the pedal on the floor and back off quickly when the engine fires up.(if it starts this way, likely you have an injector that is leaking.) What you are doing while pumping is actually giving the fuel system time to re-prime. You may have a bad regulator or pump check valve or as I mentioned, a bad injector. Aside from guessing, there are specific tests that need to be done with a high pressure fuel gauge.
OOPS! forgot to check the year! OK, check the accelerator pump (look down into carb and move the throttle linkage. You should see a squirt of fuel ...if not, it's bad). Also check fuel pressure (with a gauge...should be from 5-7lbs psi running) check fuel delivery...should be close to half gallon with fuel line disconnected from carb and re-directed through a hose into a container. run time is from start up to when carb runs out of fuel and engine stalls) Delivery is influenced by pump condition and filter.
Sorry for the other info...after a while I tend to forget there were carbs in the world (actually like them better though)
Two other items I forgot...There is a "sock" filter inside the tank that sometimes can get plugged up, especially on older cars. Also, make sure the fuel line is intact. A mechanical pump pulls fuel. a pin-hole can permit just enough air into the line to make starting difficult. Generally they wont leak much and only will show a damp spot.
Hey!!! That's not fair!!! You didn't mention spark so I thought you'd already narrowed it down to a fuel problem!!!!
Well, Glad you got it running! Tough sometimes to do this by "remote control"...stuff I always test, I don't always cover when I post, or I'd need to write a book every time!!!
Good luck with it!!!
PS: there's always a "sock" filter in the tank unless someone removed it. (for future reference.)

Hi I'm litoshop if you have to try to start more then once then your having a fuel pressure problem check the fuel pressure regulator and the fuel pump when you try and try that means you building up the fuel pressure till you get enough to start good luck if this information has been helpful please let us know thank you

My wagoneer is not fuel injected it is has a carburetor.
Thank you thundergod. I just replaced the fuel filter and accelerator pump. Still not starting right. I will check fuel pressure and delivery next.
Okay, checked fuel pressure and delivery, and they seem to be just fine. The fuel line is in good shape and I dont think there is a "sock" in this tank. Now I cant get it to turn over at all. Uggghhh!
Horray!!!!!!! It was the ignition module. Pulled one out of my other wagoneer and now she starts right up!!!!!!!!! Thank you for your help.
