Hi as for the fuel tank problem ? this is a vacumm problem created by the fuel pump workinh hard to draw fuel thus creating a vacuum inside tank suggest you ckeck the ventilation pipe from tank (under n/s/r wing along side filler pipe to see it is not kinked or blocked preventing tank to breath as pump draws fuel ?? as for excess fuel consumption? have you checked the air filter? remove it and check underneath ! this will give smoke you mention and you will have to press throttle more to overcome restriction air flow so more gas is more fuel used and little air to engine ? if you say engine stalls this is probably a result of tank vacuum and more fuel than air ?? hope this helps you sort it?

98 hyundai sonata obd II port has no power or comunication with my scaner

If you connect a scanner to the OBD2 port and the vehicle then runs fine? Then you have a problem with a ground. Top of the DLC is pin 4 and 5 that is the ECM body ground. pin 16 is battery volts 12vlts.

some of these have had problems with the dash assembly causing alot of problems with gauges and lights and speedometers.if there are no codes in the computer and weren`t any before you replaced the vss sensors then you spent money you didn`t need to.

I have a 1990 exel gls with a 1.5 4 cylinder port fuel injected. The original ecm would no longer run the engine, but will still comunicate with my scanner. I have tried 2 different ecm's which will run...

Heres a TiP for ECM malfunction!
Replace all the CAPACiTOR inside ur OLD ecm, 'cause thats the part of the circuit that breaks down!
I have repaired a LOT of ECM, and it works!
Try that if u couldn't get a NEW one!

The engine light is on and i need help to take it off. also their is a fuel pressure sensor condition.

The way to turn off the check engine light is to have the codes scanned and the problem repaired. Todays newer GM vehicles use several different comunication protocals for the different computer systems. The latest scanner technology is needed to scan and clear codes. Just disconnecting the battery does not work anymore.
