SOURCE: car won't start

There is a recall on this model for problems with the Engine Control Module/Coil Pack. This causes the engine to not start. Take it to the nearest Saturn dealer and get it repaired free of charge. This problem can eventually burn up your catyletic converter which will lead to much more costly repairs. There are actually 3 recalls on this vehicle. Take it to the dealer and get it taken care of. It will be like driving a new car once the repairs have been made!

SOURCE: 1993 Saturn SC 2 starts but wont stay running

Engine coolant temp sensor, If you pull it you will be able to see if it is cracked.. I don't know why but the original sensors they designed the ceramic tips crack around the tip of the head.. It will make the car nearly impossible to start smoke when cranking the engine, and idle really rough racey infact. 15 dollars or so let me know if that worked for you

SOURCE: 94 saturn 1.9L flooding out

i bet the coolant temp sensor is bad,,,when the sensor cracks coolant leaks into and wrecks it and then the coolant leaks thru the sensor and into the harness,,,and this causes the car to dump too much fuel because the computer is seeing a temp that is not real and therefore the air fuel mixture is off and flooding the car,,,typical issue,replace the coolant temp sensor and then harness,,like $75 for both at saturn,,do not by the aftermarket ones,yes the cost less but they are junk and will not work either,,,also i bet if you put the gas pedal to the floor or pump it when this happens i bet the car starts and smokes when it does,,,,saturn redsigned the sensor for this reason,it was plastic and they made it brass so now it can not crack and leak,the aftermarket ones are still plastic junk

Are you one of those people who TOP OFF the tank when filling up?

When the EVAP recovery system soak with few ounce of gasoline......the trap vapor will take few days escape.

EVAP system is design to handle fuel vapor. Few ounce of gasoline can damage the fuel vapor recovery relay and decrease the service live of the recovery lines.

=========

You can accelerate the process by locating the charcoal canister (near the nose of the car and same side as your gas filler door)

MOVE the car to outdoor.

Disconnect the EVAP line and let it air out by itself.

DO NOT introduce any heat source or fan to speed up the process.

Reconnect this EVAP hose and use a small amount of starting fluid at the intake manifold.


Please post more information by Clicking on the comment link.

I will follow up.

1999 chrysler 3.5 lhs fuel not going to injectors


Then your fuel pump is not working, or your fuel filter is blocked. You will probably have to check your fuel pump circuit if you have no fuel pressure in the fuel rail, where the injectors sit. There is a fuse for the pump, usually in the under hood fuse/relay block. That is probably also where the fuel pump relay is located. You should hear or feel this relay click when the ignition key is cycled from off to on. Also, when the key is turned to on, you should hear the fuel pump in the gas tank turn on for about 2 seconds. This will put the pressure in the gas in the fuel rail, for starting the engine. If you don't hear the pump turn on for that 2 second period, it is probably a bad fuel pump. But know the fuse is good first.

My car wontturn over in the morning. I changed to fuel pump and fuel filter. It cranks but wont turn over, then after a while it starts. What could be causing this


Fuel pressure regulator is a good place to look. look at the extra injector that enrichens the mixture on a cold engine too.

The regulator is probably under the intake manifold along with your injectors...the pump is in the fuel tank and the filter is usually on the firewall...

what is the fuel pressure with key on and engine off? since you mentioned spider injector assembly it has to be a vortec engine that requires 55psi to open the poppet valve in the injectors just to start.

My 2000 VW Jetta won't stay running


not the fuel relay. the pump may not have enough psi to pump properly. and you ould have a blocked fuel filter/ ethanpl das has been none to clog lines,fuel pumps, and emissions.and injectors. <p>
Change out your fuel filter first. Add a can of SEAFOAM to you fuel(parts stores). after changing filter. let SF sit in tank for 10-20 minutes in fuel. It will help dry the water that ethanol produces..,<p>
If it turns over faster, and wants to start, that is a sign of EGS(ethanol gas syndrome)/ let it sit another 20 minutes and try to start. If it won't fire through the injectors, replace the regulator(which is also damaged), and that should fix it. Also have a psi done on your fuel pump. good luck

Low fuel pressure


U 1st need to test fuel pressure at the fuel pressure test port on the top of the engione in the fuel supply rail to the injector tops, it looks like a metal tire vale stem, u will need to buy a special fuel pressure tester to do this test. U should have around 55-60 PSI at idle, it should go up when u gun the engine but never go down, if it goes down the fuel filter or pump are suspect.
