Filter has been changed multiple times, fuel pump replaced, injectors re-built, injector pump re-built and now they want to replace the tank and fuel filter assembly. There''s not much left to change. Has anyone seen this and if so, what fixed the problem?
SOURCE: misses and lots of white
first question is it smoke or steam ? if if ligers in the air behind you as you drive with little dissipation or if its steam it will dissapear more quickly . either way , head gasket is first . once saw a car do that excessive engine oil put in by owner . giant flumes of white smoke . if you ever want a true smoke scren to get away then adding about 2 to 4 quarts of oil extra . man it is something to see

SOURCE: No/Low Fuel Pressure after replacing in-tank fuel pump & filter
Need to have the fuel pressure checked at fuel rail to know for sure if there is a fuel pressure problem for sure. There may be a in line filter as well, you can also do a check of the pressure regulator by pulling the vacuum line off of it then try starting the car with it off and see if it runs, if it does the regulator is bad, but IF it doesnt run doesnt necessarly mean it is good, a lot of fuel filters have a bypass wich allows the gas to bypass the filter when it is full bad thing is the debris can then plug the injectors causing problems, or there could be a loss of signal to tell the injectors to give fuel to the cylinders from an electrical or a sensor failure. So it is best to test the pressure to know for sure if it is in the fuel line or the injectors if it is truly being starved of gas. hope this helps

Missing is usually associated with the ignition system. Check the ignition module and possibly try to check the individual spark plugs. The easiest and safest way to do this is by using an induction timing light and look for inconsistencies in the spark pattern of each plug lead.

loosen one fuel line to one of the injectors, try to start the truck and look for the fuel to spray out of the line. it should spray rather hard if the injector pump is working right. if it just dribbles or trickles out you have a weak pump.
