Virtual Technician :

Hello, My name is XXXXX XXXXX X will try my best to help you with your vehicle issue.

Expert:  Virtual Technician replied 1 year ago.

I'm going to need to ask some question: Please copy and paste with your answers:

1. What size engine?

2. Was there any warning lights on prior to this happening?

3. Has there been any recent service work to the vehicle?

4. Do you have access to a scanner?

5. Do you have a fuel pressure tester?

6. Do you have a spark tester.

Sorry for all the questions, but we need to get ME up to speed!

Thanks,

Rich

engine size is a 1.8, check engine light would come and go, no recent service work has been done, we have a small hand held that we have never used it is a obd2, we have no fuel pressure or spark plug testers

Expert:  Virtual Technician replied 1 year ago.

Do you have any codes in the system?

Can you get ahold of spark and fuel testers? We are surely going to need them

Customer: replied 1 year ago.


we can but will have to buy them. as far as the codes, i'm not sure what you mean. we can't find where the reader plug in for the computer is located on this vehicle. we have on the other two but this one is lost to us

Please note: Not every answer I give you is something you were hoping to hear, even though it is true.
Such as; (it's more expensive than you wanted to spend, or you will need to have a professional repair shop do the diagnostics and /or repairs due to complexity reasons).

The Data Link Connector MAY NOT BE the usual type - Suzuki makes all their own stuff - do you have a reader that will do your vehicle?

See Figure ATTACHED & look at #15graphic

Customer: replied 1 year ago.

no we do not

Expert:  Virtual Technician replied 1 year ago.

Ok - we'll see if we can work around that. (Might come back to haunt us)

Let me know when you have the fuel & spark tester ready.

Customer: replied 1 year ago.

where do we test for the fuel filter tester and the spark plug tester?

Expert:  Virtual Technician replied 1 year ago.

We are going to test any 2 cylinders (spark plugs) to make sure we are getting spark.

For the fuel pressure test:

Fuel Pressure Test (Sidekick & X-90)

  1. Start engine and allow it to reach normal operating temperature. Turn ignition off. Release fuel system pressure. See RELIEVING FUEL PRESSURE . Remove plug bolt on fuel rail. Install coupling, pressure gauge and hose to fuel rail. See Fig 1. Verify battery voltage is 11 volts or greater.
  2. Turn ignition on to operate fuel pump for 3 seconds. Turn ignition off. Repeat 3-4 times and check fuel pressure. See the following tables:
    • FUEL PUMP PERFORMANCE .
    • REGULATED FUEL PRESSURE

      Start engine and allow it to reach normal operating temperature. Measure fuel pressure at idle. Turn ignition off.

  3. If pressures are not within specification, check for faulty fuel pump, pressure regulator or restriction in fuel system. See CIRCUIT TEST B-3: FUEL PRESSURE INSPECTION under CIRCUIT TESTS. Repair as necessary. Release fuel pressure and remove fuel pressure gauge. Reinstall plug bolt on fuel rail. Start engine. Ensure no fuel leaks are present.

CIRCUIT TEST B-3: FUEL PRESSURE INSPECTION

Sidekick 1.8L

  1. Check fuel pressure as ignition switch is cycled on and off. See FUEL SYSTEM PRESSURE under FUEL SYSTEM . If fuel pressure is 31.3-36.9 psi (2.7-3.1 kg/cm2) and holds at 28.4 psi (2.0 kg/cm2) or greater for one minute after fuel pump stops, go to next step. If fuel pressure is not present, go to step 3). If fuel pressure is as specified, but does not hold, go to step 4). If fuel pressure is low, go to step 5). If fuel pressure is high, go to step 6).
  2. Start engine and allow it to reach normal operating temperature. If fuel pressure is 31.3-36.9 psi (2.2-2.6 kg/cm2) with engine at idle, fuel pressure is okay. If fuel pressure is not as specified, check for clogged vacuum passage for fuel pressure regulator or faulty fuel pressure regulator. Repair as necessary and retest system.
  3. Pinch fuel return hose. Turn ignition on. If fuel pressure increases, replace fuel pressure regulator. If fuel pressure is not as specified, go to CIRCUIT TEST B-2: FUEL PUMP CIRCUIT INSPECTION . Repair as necessary and retest system.
  4. Disconnect fuel return hose from pressure regulator. Connect a separate hose to pressure regulator and insert hose end into a container. Recheck fuel pressure. If fuel is discharged into container, replace fuel pressure regulator. If fuel does not discharge into container, check for leaking injector or fuel rail, faulty fuel pump check valve or leaking fuel pressure regulator diaphragm. Repair as necessary and retest system.
  5. Pinch fuel return hose. Turn ignition on. If fuel pressure is 64.0 psi (4.5 kg/cm2) or greater, replace fuel pressure regulator. If fuel pressure is not as specified, check for clogged fuel filter, restricted fuel feed hose, faulty fuel pump or fuel leakage at hose connection in fuel tank. Repair as necessary and retest system.
  6. Disconnect fuel return hose from fuel pressure regulator. Connect a separate hose to pressure regulator and insert hose end into a container. Turn ignition on. If fuel pressure is 38.4-44.0 psi (2.7-3.1 kg/cm2), repair restriction in fuel return hose. If fuel pressure is not as specified, replace fuel pressure regulator and retest system.

the whole problem is we can't start the vehicle, that is the original question. sorry

Expert:  Virtual Technician replied 1 year ago.

For the spark test - we are going to be checking it while cranking

For the fuel test I included the procedure to show where to hook the tester up to but we are also going to be getting a fuel pressure reading on just "key up" and then also when cranking.

For these tests - we don't need the vehicle running -we expect it not be...
