Car wont crank but will start

Car wont crank without starting fluid but when I put it in it. It will crank and stay running and if I turn it off and right back on like seconds later it will crank but if I let it sit there I have to use starting fluid again. I can drive it until I shut it off with the fluid in it.

    You need to scan your PCM to see if you have any DTCs stored.

    The coolant temperature sensor is failing. Usually the engine will be slow to start the first time. Turn it off and it will start normally. sometimes will not start cold. There are two sensors one for the gauge and one to the computer that meters fuel to the injectors. This one is located near the thermostat housing has a two wire connector (19MM deep well socket to remove)

SOURCE: Have a1998 astro van that wont start until I spray

The first thing you need to check is fuel pressure. This type of fuel system requires a minimum fuel pressure of 56 psi to start. Anything less, even as little as 1psi. And it will not start. It starts and runs when you add the starting fluid because the poppets (the mechanical injectors located at each cylinders intake runner) require less fuel pressure to operate when the intake is under vacuum.

This is a classic symptom of low fuel pressure. A new fuel pump is the typical fix for this problem. Don't skimp on quality if you do need a new fuel pump. They are not all the same.

Truck wont start


Starter fluid won't work if the starter won't turn the engine over.

Get the battery load tested...it may not have enough juice to start the truck but have enough to light up the lights

check your fuses and battery connections at the starter. Is the anti theft light flashing? If it is that's your problem. Wait 10 minutes insert the key...wait for the theft light to go out before trying to start.

if that doesn't work you will need to get the starter checked...which means you will have to take it off.
