Question about Cars & Trucks

Open Question

1988 Nissan Pulsar SE Engine is CA18DE Fuel pressure is good@ 68psi, still have spark, cranks but doesn't start. Fixed the tps and car almost starts. Then it backfires.

So i tested the tps for voltage it sits @ 9.48 volts and drops to 0 volts when throttling. Is that normal?? While i was testing i kept hearing a clicking noise like a bad solenoid. so i traced it to the fuel system in the engine bay. The fuel pump relay is new and i still have the old one. But as this "solenoid" clicks the fuel pump corresponds with the clicking. not sure where to find this "solenoid." Any Ideas??? I was told that it could have a fuel pressure regulator valve or a fuel pressure solenoid. If so where is it located?? and do you have a part number??

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

SOURCE: 2000 elantra no power to fuel pump.

could be a bad earth or [ground]
the power wire ma be brocken or have a loose or dirty connection
you neeed to trace it along its lenght to determine the fault!
so start at the pump & work back
Cheers rob

SOURCE: MY Ford F-150 cranks but will not start. Check

Are you sure the spark is sufficient? I have seen weak coils cause your problem also bad coil wires loosing to much voltage to the distributor.

2004 Nissan Sentra SE-R Cranks but won't start!


It could be the fuel system.
It could either flooding or starving for fuel.
If injectors are fouled badly it will wet the plugs and not fire.
If plugs are pitted that makes it easier to flood. (check plug tip condition, check all plug wires and boots are good)

If it is starving -- fuel pump weak (going to fail).
Need to test fuel pump pressure.

1988 2.5E s10 no fuel


you mean,cranks ok, but will not start and no fuel , right>?
s10 no fuel. 1988 ( S10 blazer )
please do say , what that means.
1: car cranks and will not start. so must be out of fuel?
(over 50 causes, or better is 10 or less tests (ask)
2: same, and fuel pressure is 0 psi (spec.9-13). gauged.?
3: fuel dribble test?
4: sparks good so tired test fuel and it ran on test fuel ok? proving
loss of fueling>?
5: injector dead cranking, (eyeballs)

which was it?

1988 cars in the USA are BIG TIME TRANSITION year.
we went from CARBS to EFI.
2.5L (what is E)?
gear cam, roller HLA lifters.
your car, USA , is TBI engine,
TBI started on THIS car in 1985 (1/2 and 1/2)
Throttle body injection
an on all TBI engines, one can see it inject with eyes.
does it?
if not it can be the following things.
1: no fuel pressure, 9-13pis.
2: ECU is cutting fuel. Pressure good cranking.
2a: ECU is sending error for bad crank/cam sensors, and cuts fuel.
2b: ECU sees rpm or tacho line dead.
2c. ECU sees TPS sensor output as 4v or more cranking, this cuts all fuel.
3: if ECU is happy, it sends 12vcd to the pump, cranking.
all tests must be dont cranking or chase tail.

Immobiliser does not work - engine immoblised. Rest of electrics operate normally.


WHEN U SAY WNT START DO U MEAN CRANK OR JUST TURNS OVER WITHOUT RUNNING.. IF IT TURNS OVER AND DOES NOT START IM ASSUMING U CHECKED FUEL PRESSURE. IF SO CHECK UNDER DASH memory fuse. also check ignition fuse

Car stopped while driving. Tried to start it , but to o avail. Turns over , but no spark. Changed coil changed distributor changed rotor and still nothing. Any ideas?


Hi, you will need a voltmeter to diagnose the problem. Set your meter to DC, turn the key on, and check the voltage at the positive coil terminal (black wire with white stripe) with the other probe at engine ground. If no battery voltage, suspect your ignition switch or fuse. If you have battery voltage to the coil, next set your meter to AC and check voltage across the coil primary winding (black wire with white stripe and other black wire) while someone cranks the engine. You should have at least 1 volt AC or more. If no AC voltage, suspect your crank angle sensor inside the distributor. The distributor would have to be replaced, so you would want to be sure it's bad. There are some specific tests you could run, but I would need to know the exact engine you have to provide correct test procedures.

TESTING

E16i, CA16DE and CA18DE Engines
See Figures 1, 2 and 3

Fig. Fig. 2: Crank angle sensor testing-E16i engine


0900c152801ce40d.jpg

Fig. Fig. 3: Crank angle sensor testing-CA18DE engine

  1. Disconnect the CMP electrical connector.
  2. Turn the ignition switch to the ON position.
  3. Using a voltmeter and check the CMP power source between terminal B and a known good engine ground. The voltmeter should read approximately battery voltage.

    If reading is as specified, proceed to the next step. If reading is not as specified, check power supply circuitry.

  1. Turn the ignition switch to the OFF position.
  2. Using an ohmmeter, check the CMP sensor ground circuit, by connecting the meter between a known good engine ground and terminal:

    E16i engine- terminal D . CA16DE and CA18DE engines- terminal A .

  1. Continuity should exist.

    If continuity does not exist, repair open in ground circuit. If continuity does exist, proceed to the next step.
  2. Start the engine.
  3. To test the sensor 180° signal, connect a logic probe between the following terminals:

    E16i and CA18DE engines-ECU terminal 17 and a known good engine ground. CA18DE engine-ECU terminals 21, 31 and a known good engine ground.

  1. To test the sensor 1° signal, connect a logic probe between the following terminals:

    E16i and CA18DE engines-ECU terminal 8 and a known good engine ground. CA18DE engine-ECU terminals 22, 32 and a known good engine ground.

  1. The logic probe should indicate that a pulse signal exists in both tests. If a pulse signal was not present, inspect wiring. If wiring is okay, replace the crank angle sensor.

Ford f150 1988 4.9 cranks but doesnt start


If you are getting fuel and spark, than it probably is either a bad ground, or the TPS sensor itself.

1988 nissan pulsar wont crank


The black color of the spark plugs indicate that the engine was running rich (too much fuel). The fact that they were wet tells me that there may not have been ignition. The carb being wet may be just from flooding when you tried to start the engine.
First off you need to determine if you are getting spark. You can do this by connecting one of the plugs to a wire and grounding it to the block. Have someone crank the engine and watch the plug for spark. Blue is good yellow is week. Use care holding the plug as it can give off a nasty kick. If you don't have spark than its time to check the wires, distributor cap, rotor and so on.

Engine won't crank, no spark and no fuel?


Check your map sensor which will be mounted up on the back firewall. The tube going to it is run off vaccuum so needs to be in perfect condition. I had the same probelm in the past :D on same car too lol

Nissan pulsar wont start


Replace the sparks plugs, if the car is failing on one cylinder it will be hard to start.
Check the air intake and the air filter, if air filter is dirty replaced, only to test the car try starting with intake open and no air filter, if it starts it is an air intake problem.
Check the fuel filter and check that fuel have pressure, if fuel has no pressure it is either a faulty pump or an obstructed pipe.

Common cause for car not starting is distribution, with distribution rotor you often have to replace distributor cap or coil.
If it is electronic distribution you have to scan distribution module.

If you have an anti theft system, this can also cause the car not to start, usually you unlock anti theft with car key.

If it is none of the above, it can be a car computer problem, the car computer module (ECU) can be scanned using a code reader at any good garage, in this case the mechanic will get error codes from car ECU and be able to troubleshoot further the problem.
