Thread: Car stalls when giving gas from a complete stop.

I wouldn't know what the previous owner put in as to fuel pump. But, I replaced it with an airtex. Also, this occurred before replacing the fuel pump.

I used 87.

Replaced all 3 ignition relays and test drove it around the block and I still have the issue. I decide to gun the car and blew my fuel pump again.

I remember reading some stories, can't recall what threads, of problems with the electrical connectors back by the pump that caused issues with some aftermarket pumps and low flow rates. Seems that poor connections weren't letting enough current get to the pump and so low flow rates. It is entirely possible that a bad connection can cause excessive current drain which would blow your fuse.

Inspect the wiring and clean and dirt or corrosion, replace connectors as necessary. You may need to pull the fuel pump and inspect the connections inside the tank as well, if there is corrosion there, replace as well. Once the bad connections are fixed up, you should be good.

Do NOT put a larger fuse in there, that's only going to cause something else to blow to protect the beefier fuse. You'll melt wiring, blow relays, or worse.

Today, I tried unplugging the connector at the fuel pump to see if the fuse will blow and it didn't. Checked the power wires from the pump to the fuse and it has never been touched. Checked all my grounds and vacuum hose to make sure they were intact and they were good. Last night I did more research and came across a post about the charcoal canister saying it regulates fuel pressure in the tank to the intake manifold. Was consider replacing it till I say the price on it. I'm leaning towards something that has to do with fuel. Earlier I drove it to the parts store and it drove fine till I gun it to see if it will blow my fuse and it did.

Where would I find new connectors to replace it if I decide to go down that route? I was thinking only the junk yard will problem have it. Thanks.

Junk yard may be your best place, at least cheapest. I don't buy new unless I have to.

Try this. Loosen or remove your gas cap, then "gun it". Having the cap loose or removed would eliminate vaccumn pressure in the tank.

I was thinking about getting a new gas cap, too. I had my cousin's buddy come over to check my work and wiring. Everything check out good, but he was stump on my issue. He rev'd it in neutral and it didn't die, up it in reverse and rev'd it and not. But, he was surprised and never seen anything like my issue on gunning the car and stalling. Also, I will be checking the igniter in the dizzy. I was thinking can the ignition switch cause this, too.

Hate to say it, but if all else fails, and you really want to get this running right, SOMETIMES taking it to the Nissan dealer is an option. You only take the car to the dealer in 2 circumstances: 1) When it's under warranty and 2) When NO ONE else can figure out whats wrong with it.

Rewire the fuel pump with a relay. Sounds like it's arcing to ground somewhere when it wants more amps which is blowing your fuse. What was your end to end resistance on the fuel pump circuit? I bet it was really high, or intermittent.
