When i start my mach 1 it runs fine when i use it for 5 to ten minets then when i go up a hill it bogs down and doesnt move and will die


Sounds like either your fuel pump and or fuel filter is bad. Change fuel filter first and try the hill. If it still bogs down sounds like fuel pump is almost ready to die. Get a pressure test run on fuel pump.

If above does not work then it maybe maybe your catalytic converter. Have it checked. Good luck

My 92 Chevy with a 350 TBI.new plugs set .035 new cap new rotor. Starts up ok idealso good oil pressure is good water temp is good. Interstate holds 80 no problem. But at take off she bogs also low rate...


Well if the timing mark is jumping around that's a good sign that the timing chain is streched and there is play in the chain that could cause the timing to be off does it ever stall out after it bogs and going up hill on the interstate that's your over drive kicking in and out trying to keep you at speed try timing it at the correct timing then take it on the road when you start going up a hill take it out of over drive see if that stops the shifting up an down good luck

Why does my car bog down and wont accelerate up a hill?


Usually a sign of a fuel problem, either too much or too little.
Too much could be several problems including a clogged air filter, too little could be a weak fuel pump or other issue.
A mechanic would check fuel pressure and air flow first.

1998 GMC Safari van won't start.


The ground should connect to the motor and the motor should connect to the body or chassis. Pour some water on the connection to the engine and the battery terminals. If it is a bad connection things should improve. If you jump start, the donor vehicle needs to be running at a fast idle.

I went to start my 200 ford windstar van and it just clicks. Lights come on but wont turn ove. Is the battery bad or what? WE also have had very cold bad weather could this make the battery go bad?


It sounds like the solenoid that activates the starter is activating, but there isn't enough juice to turn the motor. You say the lights come on, but test it by putting on the interior light, then put on the headlights, if the interior light dims or goes out the battery is almost certainly dead. It might be that you left something on and the battery drained, but sadly, poor batteries will fail completely in cold weather and that's end of life. First step is a jump start from a neighbour. If that starts it, run the vehicle around for half an hour and see if that has recharged the battery. When you come to turn it off to test it, PARK ON A GOOD HILL! Then if the battery is still dead, you can use the hill to roll down and bump start the vehicle (IF ITS A MANUAL OF COURSE). If the jump start fails, If the lights remain on and bright when you test, then you have a starter fault (Probably the starter motor its self). Expect it to be the battery. What you describe is a 90% probability that it is the battery

First check for any cracked pipes leading into the intake manifold If all OK (with no codes showing it probably is OK) try checking the fuel pressure regulator. If you smell fuel from the pressure regulator vacuum side arm (when the vacuum line has been disconnected) it needs to be replaced.
