TEST 2: Using Starting Fluid To Confirm Lack Of Fuel
If your 2.2L Toyota Camry ‘cranks but doesn't start’, and you suspect that the fuel pump is behind the problem, then the first test I recommend you do is a starting fluid test.
Spraying starting fluid, into the intake manifold's throttle body, is probably one of the oldest tests of any mechanic's bag of tricks. It's one I've used a lot to good effect.
The most important thing to keep in mind, is that to get an accurate result from this test, you need to first make sure all 4 cylinders are getting spark. This means you need to check all 4 cylinders for spark with a spark tester.
IMPORTANT: This is a very fast and easy test but you do have to take one very important safety precaution and this is to reconnect the air intake duct after spraying starting fluid down the throttle bore (although you don't have to fasten it). This will prevent any backfire, that might occur, from scaring the heck out of you when cranking the engine.
This is what you have to do:
- 1
Remove the intake air duct from the throttle body. You don't have to completely remove it, since you'll have to reconnect it in one of the next steps.
- 2
Open the throttle plate and spray starting fluid down the bore.
As a safety precaution reconnect the air duct after you have sprayed a good squirt of starting fluid (but you don't have to tighten the air duct's hose clamp). - 3
Crank the engine once the air duct is back on and you're clear of the engine compartment.
- 4
The engine will start momentarily and after a few seconds will die if the fuel pump is not working.
If the fuel pump is working, and thus sending fuel to the fuel injectors, then the engine won't start at all.
OK, let's find out what your results mean:
CASE 1: If the engine started and ran for a few seconds. This test result tells you that the no-start problem is due to a lack of fuel.
Your next step is to check to see what the fuel pressure is with a fuel pressure test gauge. Go to: TEST 1: Checking Fuel Pressure With A Fuel Pressure Gauge.
CASE 2: The engine did not start, not even momentarily. This usually means that a lack of fuel IS NOT the reason your car is not starting.
Now, remember what I said about this test not being very accurate? Well, I suggest you do one more test and this is to check the fuel pressure with a fuel pressure test gauge. Go to: TEST 1: Checking Fuel Pressure With A Fuel Pressure Gauge.
Jumpering DLC Terminals +B And FP To Activate Fuel Pump
The diagnostic link connector (DLC) is usually located on the right side (passenger side) of the intake manifold.
To test the fuel pump's pressure output, we need to jumper the diagnostic link connector's (DLC's) terminals labeled +B and FP. The photo above and illustration below will help you locate and identify these 2 terminals.
Location Of Fuel Filter's Banjo Bolt (Union Bolt)
NOTE: The photo above is of a 1998 2.2L Toyota Camry's fuel filter but applies to all 1992-1995 2.2L Camry's as well.
The fuel filter's output fuel hose connects to the fuel injector rail. You'll need to replace the banjo bolt (the orange arrow is pointing to) and replace it with your fuel pressure test kit's fitting. Once the fitting is in place, you'll connect the fuel pressure test gauge to this adapter (fitting).
Where To Buy The Fuel Pump And Save
The fuel pump in your 2.2L Toyota Camry is located inside the fuel tank. The fuel pump can be bought in any auto parts store, but I think you'll find the better price online. The following fuel pumps are pretty good deals:
Not sure if the above fuel pumps fit your particular 2.2L Toyota Camry? Don't worry, once you get to the site, they'll make sure it fits by asking you the specifics of your vehicle. If it doesn't fit, they'll find you the right one.
