Ok I did the mod and it primes when you go key on but when cranking it you can see the test light flashing (not staying steady) and then when it starts it stays steady is this what i am looking for? i don't have gauge for fuel yet but the lift pump is from parts store new and only 1000 miles old so far. I can tell right off the batt something is different because it cranks and lights first hit of the key where as since installing new lift pump it would crank a few times and some times you had to try 5 or 6 times before it would start! I thank you guys very much for the modification its a life saver! Question now is I know its just a bandaid to my injection pump's problem, I have 155,000 miles on truck guessing same on injection pump what should I expect to go out next or how long? Should I be saving for new injection pump? Truck runs great now starts great just worried about injection pump now! Thanks in advance. CD
