Hi,

There is a chance the fuel injectors are not getting a signal to inject fuel or they are clogged from old fuel. If it starts when you feed it fuel, then it isn't an ignition problem. At this point, I suggest two things. First, I need you to check for diagnostic trouble codes. This vehicle has an OBD1 system and you don't need a scanner to get codes. Take a look through this link. It explains how to get codes from the computer.

https://www.2carpros.com/articles/toyota-trouble-code-definitions-and-code-gathering-method-1990-1995

Do that first and let me know what codes are found.

Next, I need you to check for an injector pulse. Here is a link that will explain how to check for a pulse. If there is one, you will need to remove the injectors and check their condition. If you continue through this link, it will show you how to test the injector one it's out of the vehicle.

https://www.2carpros.com/articles/how-to-test-a-fuel-injector

Okay, that will get us started. Here are a few links you may find helpful when testing:

https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester

https://www.2carpros.com/articles/how-to-use-a-voltmeter

https://www.2carpros.com/articles/how-to-check-wiring

Let me know what you find or if you have questions. Also, see if you use starting fluid to get it started if it will stay running. If it does, there could be an issue with the cold start injector.

I will watch for your reply.

When we first tried it with regular fuel in the throttle body it tried to start but then it suddenly stopped trying to fire. We did find a blown EFI fuse but it was replaced. We definitely have fuel in the cylinder now after changing the fuel pump, the fuel filter, and flushing the lines. The plugs are wet with fuel when we pull them out now so I know there is fuel getting into the cylinder. We also checked the spark by pulling the plug out and grounding it and they all seem to have good spark. It's odd it has spark, fuel, and compression but no fire.

Hi,

Okay, if you have spark and fuel it should run unless one of the following is an issue.

Low engine compression

Engine timing off (which usually will make it sound differently when cranked)

Fuel pressure is too high and flooding the vehicle.

If all of the above checks good, the engine has no choice but to run, so we are missing something. Do me a favor. Record the engine when you are trying to start it so I can hear what it sounds like. If to you it sounds normal, then I need you to perform a compression check. I would also confirm fuel pump pressure isn't too high.

_______________________

Here is a link that shows how to perform a compression test. You will need a compression gauge, but most parts stores will lend or rent one to you.

https://www.2carpros.com/articles/how-to-test-engine-compression

I would also just confirm that fuel pressure isn't too high. There could be an issue with the regulator.

I can usually tell if there is a timing issue just by hearing it. So, if you could record it, I may be able to tell. If that isn't an option, then the compression test is necessary. If timing is off, compression will be low. Please understand there are other things that can cause low compression such as a head gasket, but in most cases, that would not affect all cylinders.

One more thought. When you checked spark at the plugs, was it a hot blue snapping spark or was it more orange or white in color?

If the timing belt jumped or has broken, it will need replaced. I have all the directions step by step, so let me know if that is an issue. You may need to remove the timing belt cover to inspect it. I do have good news in all of this. If it is the timing belt, it really isn't that big of a concern. These engines are non-interference engines which means there won't be internal damage. So many cars today are the opposite.

Let me know what you find. I will watch for your reply. Don't worry, we'll get it running.

Thank you for your help. We really do appreciate it. The compression check showed 110 in all cylinders after about 3 cycles. We did try disconnecting the injectors and it still would not start with the fuel that was in the cylinder. I will try to get a video of it tomorrow but it does sound like it cranks for a few seconds and then chokes. We try again and same thing. We open up the oil fill and see the cam spinning so we know at least the timing belt is not broken. Thank you again for your help and I look forward to hearing what you have to say.

The choke sound could be related to timing if it is firing at the wrong time. I will wait to hear it. With that much compression, fuel, and spark, it should start. I have a feeling that we jumped time. Please reconfirm the spark. Make sure it is a hot blue spark.

I dont think I had the spark plug grounded well for that video I apologize but it normally is bright and white.

Hi,

It sound normal cranking except at the very start. By any chance, did you turn the distributor? Does it always act the same way?

At the start of your video, it sounded like there was a timing issue, but it went away. To me, it sounded like it was firing at the wrong time. After that, I didn't hear any firing.

Let me know,

Joe

It normally will sound like it's trying to crank then bogs out. Then you try again and then it bogs out. We did remove the cover from the timing belt and when the crank was at TDC the dot on the cam pulley was at about 2 o'clock and I think that is suppose to be straight up. Not sure on that if you can confirm. We ordered a new timing belt and are going to try that. No we did not remove the distributor just changed the coil in the distributor and checking the cap and rotor. Thank you again for your help.

Thank you very much for your help. We changed out the timing belt yesterday and it started right up. The timing belt ended up jumping almost 5 teeth. Thank you for pointing us in the right direction and checking the alignment of it. We assumed that since it was turning the cam that the belt was good but didn't realize about it jumping teeth. Now it just appears that the alternator is not charging at all so on to the next thing, lol.
