New plugs wires air filter oil change oil filter. Cleaned throttle body and replaced gasket 3 weeks ago. Had a rough idle before tune up and still does. Fuel filter was changed about 6 months ago. Why will truck not stay running.
Replaced fuel pump and still won;t start.
it just started. i smell the coolant fluid inside the truck when i drive. is this a big problem?
Stalls out immediatley dies.Wont stay running!No trouble codes!
Head lights work turn signals work brake lights work no running lights or dash lights.
The other day on my way home it just feel off/lost power. Today it was hard starting, sound like it was flooding of starving for fuel. Made a quick trip, then went to make another and it started ran for about 30 feet (poorly) and died. Wouldn't start for a while, then 30 minutes later started it and put back in the garage. About an hour of watching utube videos I went out and it started up, still sounded like it was loading up, but if I accelerated very slowly I could get it to 3000 rpms but if I tried to accelerate faster it would sound like it was loading up again.
I see some fluids by my radiator and windshield washer tank
its cold ,then goes cool to warm you can turn off for a few minutes and turn it back on and cold for about 5 miles i have had the low pressure switch replaced and the inline filter its charged and the pump is still running when its warm line are hot and cold it has a all electric control . any help will be welcome .to have cold air i have to turn it on an off every few miles .
When in park I can increase the throttle manually and it will increase but still has a little miss.
Checked fluid in front transfer case...a little low but no metal shavings.. Jacked up both front wheels and can only turn them about a half of a turn or so
If I shut it off and re-start it. The light will stay off until I start it again. Brake performance is still perfect
i think there is a faulty switch in the dash that switches from heater to vent to ac. i dont know where that is .
