I've done the hole-in-the-floor method.My 2002 starts up fine, if it ran recently, but after more than a day or so, it takes many tries to start up. Mechanic (Firestone) says pressure goes to 0 overnight. Says they recommend a new fuel pump, about $1100, which I can't afford. I asked if it could be the lines and they repeated the recommendation. I've essentially no experience as a vehicle mechanic and a small toolbox, but I'm mechanically inclined - have rebuilt lots of things - worked on my wheelchair, computers...woodworking.
Any ideas? Having found this thread, I'm thinking it's beyond me. Seems well beyond me n my toolbox if a new fuel pump is needed. Seems worth taking to another mechanic. I don't know what to look for under the hood.
I could try to find someone (in/near San Francisco/Oakland) who'll do/help with cutting a hole in the floor... but while mine is a cargo van, the floor is covered with plywood, rubber and foam mattress, and more...
I'd tell them that if they charge you $200 for the diagnostic,Thanks! Ok, I'm going to pick it up now to avoid storage fee. (They say) I owe them $200 for the diagnostic - which now I'm thinking perhaps I should argue against - at least unless they've ruled out a leaking injector, regulator etc, which they didn't indicate they had done. I have a lot to learn - I don't know what fuel trims are or how I would prime the system. By pumping or flooring the accelerator at startup? Tank is 2/3 full at the moment, as I recall. Other than this, she's been running well - no major issues - (minor stuff - main cigarette lighter outlet doesn't work, some dash lights don't work, AC knob acts up, radio knobs were stolen, had to replace the flasher twice, because I put in LED bulbs, and then the first replacement didn't last.)
