Hello! lets check the Manifold Absolute Pressure (MAP) and the Throttle Positioning Sensor (TPS) in that order...if you have a multimeter and a wee bit of experience using one both of these sensors can be tested...If not replace the MAP first and the TPS second...

The MAP has a three wire connector with wire colors Orange/White...Blue/Light Green...And Black./White...using two safety pins push one into the rear of the in-place connector into the Blue/Light Green...The other into the Black/White...connect the + probe of the meter set to read 5 volts on to the Blue/Light Green pin...the - probe to the Black/White pin...turn key to on...Meter must read at least 3 volts...If not MAP is defective...

Using the same technique lets test the TPS...Three wire connector Green/Light Green...Orange/White and Black/White...Safety pins into Green/Light Green and Blue/White...Set meter to read 5 volts...Place + probe of meter on Green/Light Green pin...And - probe on Black/White...start the engine...at idle meter must read less than 1 volt (.85)...slowly increase the idle (as best you can)...Meter should rise smoothly to 4 volts...If it skips, jumps or acts erratic the TPS is defective...See pictures below...Guru...saailer

Backfire when starting


Cars haven't had carburetors since 1985 some 29 years

1988 taurus turn off motor when trying to restart will start but backfires thru air intake and runs weak


It is likely your timing belt/chain has slipped a notch. Remove timing cover and check valve timing and condition of belt/chain. If you need help, please let us know.

Changed distributor cap and now van wont start did not have firing order . we now have correct firing order. van was possibly flooded from checking firing order. now carborator is smoking and engine wont...


I would pull the plugs and let the gas into the cylinders to dry out , you may have a hydrolock engine after putting so much gas into it , recheck the firing order to be sure is OK ususlly when you see a carb backfiring and smoking the firing order is not right

Most fuel injection systems require around 35psi in order for the injectors to function properly.

Not getting any fuel thru da engine


the car is low on compression so you could have a hole in a piston or a bad valve the pistons in this engine are its weakest point especially if you try to crank up the boost to far above stock they can only handle about 14psi with ocasional trips above that.
also these cars do not have a carb they are throttle bodie injected so if you check your compression and is ok then try injectors
