Hello and thank you for your question,

Your 1988 has two fuel pumps, the pressure pump on the frame rail and the lift pump in the tank, when it stalls have you checked the fuel pressure at the fuel rail service port? Normal pressure needs to be right at 32 to 45 PSI.

Customer reply replied 2 years ago
pressure is ok --- new inline pump. dual tanks, the same on both tanks
Ford Mechanic: Ron, ASE Certified Technician replied 2 years ago

Okay when it dies and will not start and you are sure you have good fuel pressure are you getting a nice blue spark at the spark plugs and do you have injector pulse?

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
