I have a 1988 ford van e150 302 that wont start. When it did start, it ran rough, then progress to needing start fluid to start. Now it cranks but wont start at all. It sat for almost a year with additves in gas but it does smell now unlike normal gas. It has sta-bil and gas line anti freeze as additives. A rail mount high pressure pump was put on two years ago. Could the hi-pres pump been installed backwards? Now it will not start even with starting fluid, just cranks and tries(pops and backfires a little sometimes). I towed in to a mechanic to get diagnosed. In regards to the 1988 ford van start problems, the mechanics said that fuel is bad and needs drained, that in tank pumps seem to have pressure(low pressure pumps). The rail (high press pump) they say tests 15-20 psi only.
the want to drain tanks, replace pump and "go from there". They also said a multitude of problems can happen from "bad gas" ranging from injectors needs cleaning to bent push rods, lifters and crank shaft can be damaged. All may need cleaned, fixed or replacing at and estimated cost of $1000 to $1800. Does this seem a little fishy?
Could it need the timing set? Or injectors bad? Im stumped
