Here's some reading material on the different air flow meter types and how they work:

I won't hold it against you.... :p


I'm a photographic and video restoration artist :dunno:... I've just studied a LOT of other things... Actually, I do now work in the automotive industry, but that's a very recent change.

I won't tell you do do anything which requires crazy expensive equipment without pointing out that you're going to need a shop to accomplish it. ;)

Your Job
 

Wow that took me by surprise I thought for sure you were a Toyoya certified mechanic or something. Thanks!

Heh, I've heard that once or twice before. No, no automotive schooling. I've worked with some shops before on builds and done some tuning and electronics work on the side, but I'm mostly self taught.

Still no start
 

Hello every one. I swapped out the fuel pump relay with my other car, I did the jump to test the fuel pump propped open the vane turned on the key went back to the gas cap and listened. I can hear the fuel pump running. There is a slight buzz but barely audible.

Took the wire off the jumper, took off the prop to the vane tried to start the car and it fired for about 2 seconds then died again. When I jumped it I could not hear any return flow but after cranking it for about 20 seconds I could smell fuel but still not starting.

Could it be flooded now? The T assembly that runs across the rear of the valve covers is not on tight the rubber hosing is cracking and needs to be replaced.. would that stop it from starting?

I really am getting nowhere here with this, I am thinking fuel filter now, I have swapped the starter relay, the main, the fuel pump is making sound, I have fire to the plugs and after sitting for some time it sometimes tries to fire.

Any Ideas? Thanks for your input. Scott

Update: I just went out and took off the cold start line. I jumped the box and it started sending fuel, took the jumper off and turned the key and it was pushing fuel so I am at a loss here. I suppose compression test is the next test? I am definately getting fuel Could it be flooded now after doing the jumper test?

I am so puzzled. Compression test will tell me something I guess. Just doesn't make sense that it would die so suddenly does it if it is a head gasket or bad compression doesn't that happen over time slowly? I thought you had to be blowing tons of steam or smoke before a car would eventually stop running from compression. Help?

Any ideas suggestions?
Thanks
