I dont have a ton of money and have no way to tow it to a shop as I am a single mom of three. I took fuel pump out of car and tested it and the pump was bad. Do you suspect a fuel delivery problem? If your car will start, remove the fuse or relay for the fuel pump and start the car. I have verified all fuses are good and volts are good, replaced plugs, wire, dist cap, rotor, ignition coil which is inside dist , fuel filter, fuel pump and even the circuit opening relay which is above the glove box and still not getting enough juice to the pump. It just stalled while I was driving down the road.
When I tried to restart it it would try to turn over, but there was no pressure on the gas pedal. The car has been very well maintained. But when I tried to start the car it would not start. Any advice would be greatly appreciated. Most are color coded with stripes and you can match them up.
Here's the downlow and what I've done so far. Checked the number 4 plug and it was full of oil. Does anyone have any suggestions as to what I can do to pinpoint whats going on? If the car backfires you may see a backflash flame! Sometimes it will start but then it bogs out sounds like it is starving for fuel when you step on the gas and stalls. The car was not bucking and snorting, or feeling like it was trying to get gas to the engine, It simply just lost acceleration and the gas would not fire up the engine. Let it idle until it stalls. Take off the air filter and spray a little carb cleaner in the intake manifold and crank. I would like to know where the relay is and any suggestions to fixing this problem.
Have a 1993 toyota camry 4cyl and the problem is only 7. I had it towed home and people have been saying its the fuel pump, fuel filter, and fuel relay switch. Keep in mind that in most states, for these lamps to be 'legal' and thus pass inspection , you must wire them such that: 1. Or am I even testing the right sensor? I have changed both the cicuit opening and efi relays as well as checked all the fuses what is preventing my pump from running normally? I purchased a nother fuel pump and tested it before I installed it and it operated great. That switch in the engine is slow returning somebody said that it could be a spring. Hey there everyone, I have a 1993 Toyota Corolla and am having a real issue with figuring out why my dash cluster is only half working. The vacum sensor I saw but there was no circuit open relay on the firewall.
Cleaned it up and it has not happened again. Fuel gauge and all lights function as they should. I was hoping that you guys could help me figure out which is the most likely so I could get that replaced. Then turn off the key and remove the negative battery cable to prevent sparks while you work. When you vary the resistor then the dash gauge should move and even fire up the rad fan once dash gauge goes into red band. Also do this when above is done: At the airflow meter block the flap wide open and attempt to start- Note: The airflow meter has to ground the circuit opening relay in order to power up the fuel pump.
Thankyou can anyone tell us exactly where to get find the fuel pump relay on this model? All you have to do is relieve the fuel pressure. I took pump out again and tested it the pump worked great. . The Circuit Opening Relay powers the pump. And a few days later I was getting on the freeway when my car suddenly stopped accelerating and I pulled over and it died. So you replaced the fuel pump because it didn't make noise? I have confirmed that my Temp sending unit is functional, tested it with multimeter and boiling water according to toyota's resistance specifications.
I tried testing the pump out of the gas tank by having it hook up and turning car to on and the pump would not engage. I tried listning to see if I could hear the fuel pump under my back seat and through the gas filler cap but when I turn key to on on car I could not hear the fuel pump engaging. Also, a local dealer may be willing to make a copy of the wiring diagram for you. I put in another efi relay but I did not see the circuit open relay. Any ideas Thanks My car is a 92 toyota camry, a week ago I had the driveline replaced as it was a mangled mess! I also used my powerprobe to jump the gauges on the cluster manually and they move just like they should so I know the cluster isn't bad. I checked all fuses that pertain to dash cluster and they test good. So I guess the problem has to be in the fuse or relays so I tested the fuses and all fuses tested good, my car book said to check the efi main relay and the circuit open relay.
If you just have a bunch of loose ends, then you can check your local library for the Chilton or other manual that has a wiring diagram for your model. They may only be operated with the low beams. Can you tell me where this relay is or is it my relays? Please or to join the conversation. Posted on Aug 02, 2010 Were the wires cut? If it tries to start you are going in the right direction possibly fuel pump. I thought perhaps it was discolored due to heat so I cut it all the way up to the trunk of the harness and it is definitely white. Need a wiring schematic to figure out next step. If you're on the wrong sensor then the dash gauge isn't going to alter Have to reset fault codes afterwards though if you take it too far out of expected resistance range.
You can cut them off in other words, there must be a switch installed to turn them off and 2. Theres a fanswitch just below the airbox but I don't believe that has anything to do with the temp gauge. This is what the diagram says but at the plug under the hood its a White and brown wire. There is something wrong with the wiring that means that the fuel pump cuts out once the car has started. I done what I did befor by listning for the pump to engage when key turn to on but did not hear pump engage. Jul 29, 2010 i am pretty sure that this type of car does not have a reset button for the fuel. My car would not start so the first thing I done was to check the fuel pump.
