Just bought vehicle, ran fine for one day. Now will stall while driving. Changed fuel and air filters, cleaned MAF sensor, put SeaFoam in fuel tank. Once it stalls, it is difficult to restart. What should I look for?

Thanks for the response. The engine is throwing no codes. I will see about the fuel pressure guage however.
Is it possible to have a fault without the check engine light coming on?

yes you would need to check resistance of crank and cam sensors though. we have no info on these however so you would need to check against new. typically they will have high resistance if they work when vehicle is warm or hot and not allow starting. but yours may be fuel pressure which shold be 52-59 psi if lower it's a pump problem or regulator but normally pump. should hold pressure for 5 minutes after shut down. if not a regulator

Thanks again. I will see where this goes. BTW, I checked the connector under the floor, all contacts were clean and dry. If it is the pump, is there any way to drain the fuel tank before dropping it?

if it's full you may have to go through the vent as there is a rollover valve at the input . youmight be able to slip something past it but it may get stuck there.
