Ferrari Mailing List: Re: Same troubles are back for 308

[Doug & Terri (dnt]

What if I try to put a 25A fuse instead of 16A for fuel pump ?

 

If the circuit requires a 16 amp fuse and there are no problems it wouldn’t matter if you put a 22 cal bullet between the contacts.  BUT if there IS a short circuit problem, a 25 amp fuse will just take longer to interrupt the circuit and in the process, fry the ‘consumer’ (the motor, the lamp, the wires leading to the consumer).

 

Easy peasey.

When my car stopped last week. I remember replacing a broken blue fuse. The rest were white and red. I replaced it with a red one (16A). But as much as I want to remember I don't know which one it was. Should have paid attention but I was so mad...... 

The third fuse is for the fuel pump. Blue fuse had 25A written on it. Can it be that somehow my mechanic had put this one there last year without telling me. I know I DID NOT put a blue fuse myself.

What if I try to put a 25A fuse instead of 16A for fuel pump ?

1981 308 GTSi: O.k. remember last week when the car suddenly died ? First towing in years.

The next day I cleaned the gas pump relay with sandpaper and the car started right away. I turned the engine off within 2 seconds because I was inside my garage. But this saturday and sunday I changed 5 relays (including the gas pump relay and the start injector), shot some "electrical contact & parts cleaner" inside all relays receiving ends and added a bit of "dielectric tune-up grease" on all relays. I also cleaned the 2 wires going in the 2 distributors.

Well, today was the big test. The car started on the second crank, drove onto the street, waited a few seconds maybe 20 and it died. Couldn't start it at all after that. The starter did its job and I could hear the engine almost start for a second, only to go dead again. 7-8 times like this. I pushed the car back inside again. Decided to sandpaper the legs of the brand new gas pump relay. The car starts right away. I quickly drove onto the street again, gave it lots of gas and 20 seconds later, it dies again. Just for good measure I tried again and same thing. I give it some gas, engine revps up fine and then nothing.

 

I remember someone suggesting checking the ground on the gas pump (this was changed in november 2006 along with a used accumulator). I haven't done that. I'll do this next weekend.

What else do you suggest I check ?

I really want to find the problem. I don't want to pay for another towing to my mechanic only to find out it was nothing serious.

 

Thanks!
