You
I have a 98 mustang gt automatic that won’t start. I just installed an Edelbrock victor jr intake along with edelbrock high flow fuel rails, edelbrock low profile upper intake plenum and a 90mm accufab throttle body. The theft light had been coming on before I tore it apart but is now blinking. The car started a few times was very hard starting and when it did start it had a very irregular idle like it was cammed and it smoked a lot on the first few start ups. The next day I cannot get the car to start at all it acted like it wanted to start but was boggy and being choked out. The exhaust smells strong of gas so I know that it is getting fuel. I scanned it with my scanner tool and and got o2 sensor codes so I checked and come to find out the o2 sensors have been removed and the plugs are zip tied up. But I didn’t think that was why it wasn’t starting, so I went into the active test on my scanner tool and looked everything over. The fuel tank pressure value is reading 5 which is very high I have not checked my fuel tank pressure sensor yet because I believe it is on top of the tank and I didn’t want to drop it but I plan on checking it tomorrow. My short term fuel trim is at 94 and my reference voltage value is a red 0. If I try to crank it the motor is turning over and acting choked out and will occasionally pop out of the throttle body. I have taken the gas cap off and the fuel tank pressure did not change, I have checked all of my fuses and plug connections to the engine with a multimeter. Yes the tps is getting proper voltage readings along with the iac and maf. Also when cranking the motor over sometimes the fan will click on and then off. I’m not sure if the pcm is bad or if I have a short but I’m assuming the 0 value on the reference voltage is the main cause. Sorry if I’m providing a lack of information I’m new to this and I’m doing my best, thanks in advance to any help.
