One Nasty Problem (Stalling)

gtdan · November 11th, 2007, 11:22 PM

Well today i drove my car for 2 hard hours and my car stalled. This past summer it would do the exact same thing but never took it to get it checked cause its not my dd now that i want to do gears and cams it starts to do it again and i want to fix that problem before i start modding it. do any of you know or have any suggs of why its doing that, it starts back up after 20 or 30 mins , it also sounds like its gasping for air or fuel, and rpms go down to 300 till it dies if i try to start it after stalling it just keeps doing the same thing, its almost like something needs to cool down. please help!!!!!

Sounds like a coil pack issue, or fuel pump/injectors.

MustangMatt96GT · November 11th, 2007, 11:28 PM

for a coil pack, test this

There are too things to test, primary resistance and secondary resistance. To test primary resistance unplug the harness from one of the coil packs. There will be three prongs. The outer two on the coil pack are negative and the one in the center is positive. Connect an ohmeter in between the positive and each negative. The resistance should not exceed 1 ohm.
To test the secondaries, remove the spark plug wires. Connect an ohmeter between two secondary terminals (where the wires go). They must be checked in these pairs though. 7/4, 8/2, 1/6, 3/5 (remember this is a waste spark system). The resistance should not exceed 11.5 Kohms.

would those throw a cel?

MustangMatt96GT · November 11th, 2007, 11:29 PM

it depends on the situation

MustangMatt96GT · November 11th, 2007, 11:29 PM

also hows ur battery?

gtdan · November 11th, 2007, 11:32 PM

its a red optima but i think i need a new one due to the fact that when the rpms are low the volts go down and so do the lights.

MustangMatt96GT · November 11th, 2007, 11:38 PM

have you tried chargeing that? When i had my old battery, it sometimes wouldnt start for some reason!

96GTRagTop · November 11th, 2007, 11:40 PM

my friends 98 has the same problem.......

his fuel pump for some reason won't turn on at all..... ussually after a day of sitting the car fires right back up. It does it once in a while, so he's lazy about getting it fixed, like u were

Bad ground perhaps?

who knows..... the kids to fucking lazy to have it checked out

96GtGoodz · November 12th, 2007, 04:34 PM

hard to say if i had to i would say either the battery, injectors, or air/fuel (get it checked out man)

gtdan · November 12th, 2007, 11:50 PM

what does the batt affect that it stalls, and why does it need to cool down to start back up?

MustangMatt96GT · November 13th, 2007, 12:38 AM

it just could need a nice charging, but do you have underdrive
pulllies?

gtdan · November 13th, 2007, 05:27 PM

yeah bbk's

gtdan · November 13th, 2007, 06:32 PM

how can i check my air/fuel and injectors?

MustangMatt96GT · November 13th, 2007, 10:36 PM

did you check the coil packs as i described? only way to get the A/F is get it on a dyno, or get a wideband A/F gauge. I think that this is a ground problem and starter problem, just because you have to wait for it to cool down for it to fire back up. And the pullies, is what is making the volts gauge go down and the lights dim, not the battery, but going into the winter season i suggest giving it a full charge.

gtdan · November 13th, 2007, 10:52 PM

i know but i dont have a batt charger lol

MustangMatt96GT · November 13th, 2007, 10:59 PM

my dad might let me lend you ours.
