my delta 88 has been running great, just last month I put a new oxygen sensor and a new catalytic converter on it. ran perfect. no issues at all..
went to start it to day to go some where and I let it warm up for 10 mins, then when I went back to the car to leave as soon as I stepped on the gas it stalled. so I started it back up, check engine light instantly came on and car instantly stalled again.. gave me a code 44..
it stalls within 5 seconds of starting it, don't understand the code 44 as a month ago I put new oxygen sensor and cat, any thoughts on this.. ? help please.. thank you..

44 is "system lean". Check the fuel pressure.

Yep, you'd need a gauge.
