and then something breaks…

On our way to the rallycross, we were on the I-15 when I smelled gas. A lot of gas… “Is that us?” I asked aloud. We passed a slow moving tow truck with a wreck on it and the smell dissipated. “Oh, okay. Not us…” We pulled off for the Glen Helen exit and the smell came back. “Okay – that’s us. What’s the deal?” I pulled over and hopped out. When I came around the back of the car I heard a hissing noise from the gas cap. Slowly twisting the gas cap I released what might have been 40psi of pressure. A really, really hot day. Full tank of gas. These things happen right? Later I think of the new aluminum plates reflecting all of the exhaust heat back into the floor. The same floor the brake and gas lines are attached to.

Last night I took the rallycar out to PepBoys and a date with the high pressure car wash. I picked up some essentials. Some new hose for the PCV, new wipers, spare belts, etc. I dropped 5 bucks in the ‘scrubadub’ and hosed the cement from the rallycross off. I headed home.

Less then a mile from the house, I’m coming up to a stop sign – heel toe downshift to 2nd. ‘RRRevvvvvv… stall. coast.’ I turn her off to the right and try starting again. No go. “hrmmm.” Open the hood. Check all the obvious stuff. Hop back in – cranking – not starting. I stop and turn the key off. I listen close for the ‘whirr’ of the fuel pump. I click the key forward. Nothing… No sound from the fuel pump. Bingo!

I fumble the fuse box in the engine bay open. I glance at the primer and pull the 20A fuse for the pump. Sure enough it’s blown. “Okay!” I go for the bag of fuses stashed in the car. Quickly I drop a replacement fuse in – close up the bag and start the car. “Sweet!” Off I go down the road.

In about the time it takes me to contemplate the fact that fuses just don’t blow for no reason, and that the fuel pump was probably over loaded, maybe from getting it soaked at the car wash, maybe from the other day when we were in the sun… The engine cut out again. This time I bumped it up with a 25A fuse. I gave it some time to sit. I made it barely 100 feet before it died again.

Now I’m maybe 1/4 of a mile from the house. I have 1 hill to get over and I can coast down most of the rest. The Blazer is up at the shop and I refuse to call AAA to tow me until I ‘need’ a tow. I go back into the magic tool kit and grab the solid copper wire. (don’t try this at home kids…) I pull off the coating and twist up a fuse replacement. Start the car and floor it up the hill while giving it a 10 count. After 10 seconds and the top of the hill I kill it and coast. At the stop sign I wrestle no power steering and a rolling pause to the right. One more start. I only need a 5 count this time. I get the Neon up into our parking lot.

My thinking is that the heat and pressure pushed the 10 year old pump past it’s life expectancy. I really don’t think getting the wires to it wet would be popping fuses. I really have no choice but to drop the tank and replace the pump as well as insulate all the lines. AAA Plus will be getting some use tonight.

  1. so didja figure it out??? water on insulated wires won’t cause a prob, but exposed wires could short through the water… my guess it is would be SOMEthing related to getting everything wet. normally, if a problem comes up right after doing something, that something is most likely to blame. not always, but… =)

    are you goin to market your new copper 3,000A fuses?
    ;P

    ps thanks for sharing your shade etc at the rallyx — look forward to seeing you guys at gorman. let me know if you want those tires.
    we’re not 100% we’ll make it now though. i checked out our car to figure out the problem and we’re at ~80psi on all the cylinders, so we’re pulling the motor tomorrow night to rebuild it.
    argh.

  2. New fuel pump $215
    I didn’t smoke the wires with the 3,000A fuse – so less I have to do there. :eek:
    I’m confident that the pump is the problem. I can start it and run it – but after running for 10 – 15 minutes it blows the 20A fuse. I have a feeling ‘boiling’ all the gas in the tank and running it hot for 4-5 hours on Saturday pushed the 10 year old fuel pump to it’s end.

    I took all the plates off and now I just need to figure a way of shielding the lines from the heat of the exhaust reflecting off the plates. I’m considering making some 2″ holes down the center line of the exhaust. As well as wrapping the lines in heat shielding and foil tape. Will this be cheaper then running all the lines inside the car? Who knows. There is a drag racer at the shop who might be able to give me a hand running them inside the car in time for Gorman.

    Bummer on the engine dude! I hope you have time to pull it off!
    Tires – yes – sure – bring them to Gorman and we’ll throw you some caYsh.
