i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em

SOURCE: will start then dies

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

The fuel pressure that you are getting is actually quite fine, I would begin to look at a mass air flow sensor first, then the manifold absoloute pressure sensor. Your fuel concern is over though..

You did'nt say if you have had the car (Scanned) to see if the engine control Module has stored any fault codes. You say it runs 20 miles or so before it quits. After cooling does it alawys start back up? What have you been doing to get it running again? The ECM can warm up and quit. It'll get an Troblem code about though. The no spark at the time sort of removes the Cat converter overheating and the ingtion Module ( (the coils are mounted to it). Something getting too hot is likly. Crank sensers and cam sensers both wil do this the crank senser is on the back of the block just above the oil pan. The cam sewnser is underneath the power steering pump and the connector going to it is on top of the front valve cover on the passenger side. Crank sensers will not code and still be bad. Computers if they come back on ever they will code most any problem and the code name is Quad driver failure.

Why would a 2003 hyundai elantra have a hard start issue, fuel pressure bleeds off to 10 psi overnight from 50 psi?


There are many things that can cause this issue. If repairs have been done, you want to make sure you are using the original master key as the valet key wont allow the immobiliser to bypass and start the car. Fuel pump, bad fuel filter, injectors etc. If you have a check engine or service engine soon light on the dash you can scan the codes (for free at autozone advanced auto) and post them here. With these codes i will be able to tell you almost exactly what your problem is. ECU maybe? need just a little more info/background on the vehicle. We will get this resolved

How much fuel pressure does it need to start engine


50 psi is ample to start an engine. You will need spark and compression as well . Check immobiliser operation. Check that the cam shaft is turning (timing belt) Check for spark at a plug HT lead

Engine wont start but its in fuel system


When you turn the key to on, not start, do you hear the pump turn on for a couple of seconds to pressurize the fuel system? If you do, check fuel pressure with a gauge, should be over 50 psi if multi port injection, about 20 psi if throttle body injection. If pressure is good, you may need to check the fuel injector circuit.
If no sound from the pump, you will need a voltmeter or a test light to check the fuel pump circuit. First check the fuel pump fuse. Then check for power at the gas tank on the fuel pump wire, when the engine is being cranked over. Power should be going to the pump then. If nothing, move back to the fuel pump relay-need to check for power at the relay.

2001 chevy silverado fails to start on random days, 50 psi fuel pressure at test port, a couple of hours later it starts perfectly and does so for a month or so then does it again


need to check fuel pressure before trying to start and see if it's bleeding down or staying pressurized hook gauge on and check periodically before trying to start, seems like mine done that and it was a b ad fuel pressure regulator on the fuel rail, 5.3 ? it's on drivers side rail with vacumn line erunning to it about the size of silver dollar diam.

1997 chevy astro van willn't start new fuel pump and filter pressure 50 to 60 psi ,got spark turns over


If you have spark and fuel it should start. You must have min 57 PSI fuel pressure for this vehicle to start if it is the 4.3 Vortec engine. Also the cam sensor and the crank sensor control the spark. Does it have the check engine light on and if so what is the code or codes does it have? Need more info to help you out more.

POSSIBLE CAUSE ENGINE SPUTTERING COULD BE CLOGGED FUEL FILTER,DIRTY FUEL INJECTORS.CHECK FUEL PRESSURE COULD BE WEAK FUEL PUMP.CHECK FUEL PRESSURE SHOULD BE.25 -65 PSI OR 30 - 40 PSI.

Got a 1999 gmc jimmy. Wether it is cold outside or warm my truck has difficulty starting when the truck is cold. Got new plugs wires and distributor. Fuel pump is working fine. Once it is running there is...


Common problem with these is a fuel drainback. Use a fuel pump pressure tester, start the engine, If it's multi-port fuel injection the psi should be 50psi+. If 50psi, turn off engine and notice psi drop. If fuel pressure drops off to 10 or 5 psi, try to start engine and watch for a jump in fuel pump pressure. If pressure jumps to 50psi and the engine won't start, then I would suspect a good working fuel pump, if not a jump to 50 psi, I would say bad fuel pump. Good luck, Gary

Completed tune up, drove for 2 blocks, engine shut down


Just having fuel is not enough on this engine, here are the spec's. Even 1 psi out of spec can cause a no start.

Fuel Pressure

Y132: System pressure while idling (PSI).
Y133: Fuel pump pressure (PSI) with return line briefly restricted.

Changing fuel filter


From what your describing this sounds like you have a bad fuel pump and should be easy enough to verify.Install a fuel pressure gage on the fuel rail. Cycle key on and check for a minimum of 50 PSI. Start engine and verify fuel pressure maintains at least 50 PSI during symptom.

If pressure drops, lower fuel tank to check for B+ on the Pink/Black (PK/BK) and good ground on the Black (BK) while fuel pump relay is energized. If OK, replace faulty fuel pump.
Fuel pressure should run between 50-65 PSI. Fuel pumps are a common failure item on this vehicle especialy during warmer weather.


lower the tank to get to your filter
