Question about Toyota Celica

1 Answer

01 Celica won't start, no spark no signal from ecm to the igniter on any off the 4 coils, no signal to any off the 4 injectors, fuel pump not working [pump works]. Check #1 wht at E2 battery power ok, #9 blk/org at E2 ignition switch ok, #16 blk/red at E2 ignition switch ok, #7 E2 wht/blk gound ok, #12 E3 wht/blk ground ok, #17 E4 brn ground ok, #31 E5 wht/blk ground ok. Check resistance on crank, cam, and air flow meter all ok with mitchell. IG2 and IG1 relay ok, C/OPN and EFI relay ok. When this problem started the customer was boosting his car and blow the 120A main fuse the car haven't started since. Looking for some help.

    I checked the relay and fuses and all are ok. there is power going to the coils, injectors and fuel pump.

  • evansgarage Mar 31, 2011

    12v to coil, injectors fuel pump relay and 3 power wires to the ecm and 4 good grounds.

    replace the ecm with a used ecm, still the same problem no signal to the injectors or coil. Wondering if there was something that I might have over look or didn't do right.

Sounds like there is no power to the EFI relay, there is an EFI fuse in the under hood fuse/relay box, if fuse is ok take a power probe ( by the way there are 3 EFI fuses a 15 amp and 2, 7.5 amp ) remove the EFI relay and power up terminal #3 and see if the fuel pump powers up with the key on, this is the power circuit for the coil. injectors, and fuel pump.

check this out and let me know what you find.

    so if you have power to everything, did it start? so are you saying you dont have any ground?

    if all the wires check ok from the rcm to the injectors thay they may have took out the ecm.

    looks like you have tested all the wiring sounds like you need a PCM.

    if you have mitchell system then go to engine performance, then to fuel injection testing, you will find the test for the ignating system and the fuel system, go to engine no start test follow the flow charts and they will take you to your problem, the best advice i can give you is work within your ablity, there is no shame in admiting when you are beound your means, and you need help......GOOD LUCK

My van wont start no fuel or spark ?


Sounds like it could be the ignition module in the distributor. You have a throttle body instead of a carb. The injectors get a ground signal from the engine computer when they are supposed to open. The ignition module takes a signal from the pickup coil in the bottom of the distributor and decides when to fire the plugs and also the injectors.
If the injectors and the coil has power, it could be the module or the pickup coil.

1999 chrysler cirrus 2.5l won't start


The ECM sends a GND signal to the Fuel Pump relay to switch it ON. When 'jumping' relays, there is a risk that you might feed +12V to Gnd switch line, in this case the ECM line. If left too long, this would blow the diodes in the ECM. Try using another ECM. Try following the ignition circuit from the ignition coil back to the ECM. One of the wires connected to coil should have +12v when IGN on. Sparking only happens when ECM sends GND pulses to the coil. If ECM is OK, check camshaft position sensor, which is also usually referred to by the ECM for ignition firing.

1992 celica wont start and now battery is dead


Engine starting depend on the following systems:
1. Fuel system (fuel level, fuel filter, fuel pump pressure etc).
2. Ignition system.(Ignition fuse, spark plugs, spark plug cords, distributor signal, ignition coil, and ignition switch)
3. Battery. (11.4 V - 14 V)
4. Cylinder compression. (145 psi - 190 psi, valve clearance)
5. Starter rpm (250 rpm)

2. Crankshaft position sensor.
3. Camshaft position sensor.
4. Ignition system.
5. Fuel pump control circuit.
6. ECM.
7. VC output circuit
Difficult to start with cold engine
1. Ignition system.
2. Spark plug.
3. Fuel pump control circuit.
4. Fuel Injectors.
5. Cylinder compression.
Difficult to start with warm engine
1. Fuel Injectors.
2. Ignition system.
3. Spark plug.
4. Fuel pump control circuit.

I am not getting gas or spark


The fuel pump and coil are on two different circuits.
The fuel pump is on the 20amp ECM fuse and the coil, ignition module, and injectors are on a 20amp fuse #10. But the ECM fuse could keep the coil and injectors from working.
You would need to test the fuses in the box in the engine compartment, and the fuel pump relay and coil for voltage and ground. The pump relay is grounded by the computer for 3 seconds when the engine is cranked.

The dash gauges all work , fuel pumps are both good , the fuel pumps wont come on and the truck trys to fire when i turn the ignition on but wont , could this be a fuel regulator


did you check the fuel pressure pump on the frame rail for power and ground? have you verified no ignition spark to the spark plugs? have you checked for fire from the coil to the distributor cap? does the check engine light come on when you turn the key on? have you check for injector pulse and power at the fuel injectors? if the fuel pump won't come on and you have no ignition fire and no injector pulse, all of these systems are triggered by the ECM.

MY CAR WILL TURN OVER BUT WON"T START


Check fuel pressure,spark on the ignition coils,signal on the injectors.no pressure,check the fuel filter and the fuel pump.no spark,check fuses,crank sensor,cam sensor.

My truck will not start just cranks but will not fire


Air - not likely the problem ! mechanical cable controlled throttle body

Fuel- make sure there is gas in tank! fuel pressure test at the throttle body or rails, if no fuel check power to fuel pump: ignition power to breaker or fuse, relay , power to pump at 3 pin connector near tank/frame rail on drivers side, - if pump is runniig but insufficient pressure, check for mechanical restriction: plugged filter broken or pinched line, plugged pickup tube in tank. if good pressure to rail or body, check ecm : diagnostic codes, fused power, ecm tells injectors when to open, dependent upon several sensor parameter inputs.

Spark- ignition - coil-distributor-ignition module (or coil packs)- wires-plugs-ignition module (signals coil to discharge, mounted beneath distr cap) work backwards from plugs.
